SAP IDT - Quick Guide
SAP IDT - Overview & User Interface
Information Design Tool (IDT) is a Business Objects design tool that extracts the data from different data sources using an OLAP and Relational connection to create Universes. There are different Universe parameters that can be passed at time of Universe creation.
A Universe is called as logical collection of dimensions and objects that allow business users to analyze the business data. Objects and dimension represent different hierarchies, measures, custom calculations, and attributes.
Universe can be created on the top of relational databases like SQL Server, Oracle or also on top of an InfoCube in SAP Business Warehouse (BW) system. Different types of connections can be created to these data sources like personal connection, shared connection and a public connection. A SQL or MDX statement is generated according to data source respectively - Relational and an OLAP.
A Universe created using an IDT can be used with different reporting tools in Business Objects. When a Universe is published to a central repository, it can be used in the following reporting and dashboard tools −
- SAP Business Objects Web Intelligence (WebI)
- SAP Business Objects Dashboard Designer (Earlier known as Xcelsius)
- SAP Business Objects Crystal Reports
- SAP Business Objects Explorer
Different Components in IDT while Designing a Universe
An OLAP or a Relational connection to data source
Extracting the tables and joins from Relational database or an OLAP cube.
Building a data foundation from extracted tables and joins.
Creating metadata objects from data foundation layer and these objects are managed in Business layer.
Using Universe parameters and to share the resources in Universe.
Publishing a Universe which includes Business layer, Data Foundation and a Universe connection to database
Universe can be published to the central repository to be used by other SAP Business Objects reporting applications.
Security profiles are used to provide access on Universe data and metadata objects.
IDT is primary used by application managers and report developers who wants to create analytical reports on the top of data stored in the different data sources. To create reports on top of Universes, a person needs technical understanding of IDT tool and functional knowledge of Data Warehouse.
SAP IDT - Resources
There are various resources in Information Design Tool that can be used to extract the data from data sources and to create a Universe −
Project
A Project is a local workspace where you store the resources used to build one or more Universes. This is used to manage the local objects, which are used for Universe creation. A single project can contain objects for one or multiple Universe. A local project can contain multiple number of objects like data foundation layer, business foundation, and data source connection, etc.
Data Foundation
Data Foundation layer allows you to import tables and joins from different relational databases. All the joins are imported and you can also define derived tables, custom calculations, additional joins, contexts and prompts.
Relational and OLAP Connection
A connection is used to define how data is extracted from a relational or an OLAP data source. A Universe always uses at least one connection to extract the data. You can also build a multisource that extracts data from one or more data sources using multiple connections.
A connection can be saved locally with .cnx file and all Universes created on the top of local connections can’t be published to BO repository. To publish a Universe to repository, you should use a secured central connection with .cns file.
.cns- secured Repository connection
.cnx-local unsecured connection. If you use this connection, it will not allow you to publish anything to repository.l
Business Layer
In Business layer, you define measures and dimensions. You can also apply Aggregations like Sum, Count, Avg, Min, Max.
To complete the Universe creation, you need to save the project and then publish the business layer to the repository.
UDT vs IDT
In UDT, a Universe is created with file extension as .unv. In IDT, a Universe file extension is changed to .unx file.
To open unv file in IDT, it can’t be directly opened but you can convert unv file to unx file to open in Information Design tool. You can’t open an IDT .unx file in Universe Design tool nor you can convert it to unv file.
Universe Design Tool is a single-source enabled tool. However, IDT is a multi-source enabled tool meaning you can extract the data from different data sources while creating a Universe.
| Universe Design Tool (UDT) |
Information Design Tool (IDT) |
| Universe file extension- .unv |
Universe file extension - .unx |
| You can’t open .unx file and also it can’t be converted to unv to open in UDT |
You can open unv file by converting unv file to unx file extension |
| It is single-source enabled |
It is multi-source enabled |
| It can’t be directly connected to Dashboard designer and Crystal Reports latest version |
It can be directly connected to Dashboard designer and Crystal Reports latest version |
User Interface in IDT
When you retrieve an existing Universe in IDT by connecting to the repository, following are the available interfaces. These are the same when you design a new Universe in Information Design Tool.
Local Projects
It defines the existing connection in use (.cnx or.cns), Data foundation layer (.dfx) and Business Layer that are local in Universe as shown above.
You can click on each object under Local Projects to see the details and to make any changes. Click on the connection .cns file to see the connection details. Similarly, you can open .dfx or .blx object.
Repository Resources
Once you connect to the Repository, you can retrieve all the objects that are designed and published to that repository.
To insert objects from the Repository, click on + sign and select Insert Session. Enter the system details, the username and password, and you can see all the objects in the Repository.
Business Layer
This layer contains all the classes and objects, you can check dimensions and measures that are defined in a Universe. When you publish the business layer in the repository, this shows the completion of Universe creation.
You can check the summary of Business Layer to see the number of attributes, dimensions, measures, classes, LOVs, etc.
Data Foundation Layer
This layer is used to define data foundation that includes tables from data source, joins, etc.
To check the structure of data foundation, you can click on .dfx under local projects and it will take you to Data Foundation layer and its components.
Setting and Resetting Preferences in IDT
You can customize Information Design tool user interface by setting preferences. This can be reset to default using Reset to default display option. To set the preferences in IDT, go to Windows → Preferences.
Once you click on Preferences, a new window will open. You can define preferences under General, Help and Information Design Tool preferences.
Information Design Tool Preferences
- Business Layer Editor
- Check Integrity
- Data Foundation Editor
- Languages, etc.
Using Reset to Default display option under Window tab allows you to reset all the values to default or you can also use Restore Default option on Preferences window.
SAP IDT - Creating Universe
To create a Universe in IDT, go to Start → All Programs → SAP Business Intelligence → SAP Business Objects BI Platform 4 Client Tool.
In Information Design Tool, you have to create a New Project. Go to File → New → Project. Enter the Project Name and Click on Finish.
Once the project is created, next is to create an OLAP or Relational connection to connect to a data source. A Relational connection is used to connect to the Database layer to import tables and Joins. An OLAP connection is used to connect to the multidimensional model like an Information View in SAP HANA.
Right-click on Project name → New → Select Relational Connection → Enter connection/resource name → Next.
Choose SAP from the list → SAP HANA → Select Drivers JDBC → Next → Enter details.
Enter the system details, username, password, and click Next.
Click Finish.
Under General Information → Click on Test Connection → Successful.
We have to publish this connection to the Repository to make it available for use.
Right-click on the connection name → Publish the connection to the Repository → Enter BO repository password → Click on Connect → Finish → Yes.
Once you click on finish, it will create a secure Repository connection.
.cns − secured Repository connection
.cnx − local unsecured if you use this connection it will not allow you to publish anything to repository.
The next step is to create a Data Foundation Layer on this secure connection.
Right-click on .cns Repository connection → New Data Foundation.
Enter Resource Name and click on Finish. It will show you a list of all available schemas in the database. You can add Tables and Joins from Schema to Data Foundation layer. This can be done by dragging the table or by a double-click. Apply the joins on Dimension and Fact tables to create a logical schema.
To define a Join, double-click on Join between tables. It will show you both the tables. You can select from different Joins as per data requirement and click on detect Cardinality to define cardinality - 1:1, 1:n, n:n.
Next is to create a Business Layer on the Data Foundation. Click the Save All icon at the top of the screen. Then, right-click on Data foundation .dfx → New Business Layer.
Enter Resource Name → (Generating Business Layer for Data Foundation) Finish. It will add Business Layer .blx under the Local Project.
It will show a list of all dimensions and measures under Data Foundation. You can define dimensions, measures, aggregation, etc.
To define an Aggregation, you can select from Projection Function. You can also hide few objects in the report if you want by using the dropdown next to measures and dimension. You can select Hidden for a particular object.
Once you define Business Layer, click Save All icon at the top of the screen as shown in the following screenshot.
To publish a Universe to the Repository, right-click on .blx → Publish → To a Repository.
Select Resources → Next → In Publish Universe window, select Next → Select the Repository folder where you want to publish Universe and click Finish.
You will get a confirmation that Universe published successfully.
To check the Universe under Repository, go to Repository resources and check for the Universe that has been created.
Creating a Universe on SAP ERP
You can build a universe on SAP ERP by using Data Foundation in IDT. You have to create a relational connection to ERP data source, info sets, SAP queries, and ABAP functions that are treated as tables in the connection.
You can create a single source Data Foundation to support local connections but it doesn’t support Joins and calculated columns between the tables inserted from an ERP connection.
To use a calculated column, joins, you need to create a Data foundation that is multi-source-enabled on a secured connection.
When a table is added in Data Foundation layer, the table type of info set, SAP query, or ABAP function is saved as a table property in the data foundation. To add an ABAP Function table, there is one data foundation table created to map the main function.
The table contains input columns for the input parameters of the function. These parameters can be mandatory or optional. To assign a value to mandatory parameters, you need to edit the input columns.
Limitations of Using SAP ERP
When you use measures that contain aggregate functions it can’t be used as filters in the Query Panel as the output SQL expression consists of HAVING clause, and it is not supported by the SAP ERP connection. Hence, if a measure is added that contains Aggregation function as filter, it throws an error while refreshing the query.
Creating a Universe on SAP BW
If you want to use SAP BW to design a Universe, you should use a data foundation based on multi-source enabled structure. All the tables and joins in SAP BW are automatically imported to Data Foundation. When a Business Layer is created on Data Foundation, all objects are automatically moved to the Business Layer.
If you don’t want to insert tables and joins automatically, you can unselect the Detect tables by going to advance properties while adding connection to Data Foundation.
You can also turn off insertion of Business Layer objects by unchecking the option to automatically create classes and objects when selecting data foundation in New Business Layer.
Creating a Universe on Microsoft Analysis Services
You have to create Business Layer on Microsoft Analysis Services (MAS) and business layer objects are created by default. Following is the mapping of objects in Business Layer −
Dimension − Analysis dimensions are created in the business layer for each dimension in the cube.
Display Folder − Folders are created in the analysis dimension to contain the hierarchies in the display folder.
Hierarchy − For value-based (parent-child) hierarchies, a value-based hierarchy is created in the analysis dimension. The attributes are created in the Attributes folder in the hierarchy.
Attribute Hierarchy − Attribute hierarchies in the cube are created as level-based hierarchies in the analysis dimension.
Named Set − Named sets are created in the related analysis dimension, in the folder Named sets.
Measures and Calculated Measures − Measures and calculated measures are created as measures in the appropriate measure group folder. A measure attribute is created for the formatted value.
Creating a Universe on SAS
You can build a Universe on SAS by using multi-source enabled data foundation and using a secure connection.
Connection to SAS data source are managed by data federation service.
Multilingual Universes
You can also create multilingual Universe in Information Design tool. This allows you to use multilingual solution by using single Universe metadata model.
Following are the steps to use multilingual Universe for report creation −
Step 1 − Use Universe designer to design Universe in source language in IDT.
Step 2 − Use translation management tool to translate the metadata in the data foundation and business layer.
Step 3 − Use report designers to build the reports on the same Universe, which can be displayed in different languages as per user preferences.
Step 4 − Go to Information Design Tool → Preferences → Preferred Viewing Locale determines the language of the metadata and data in the Query Panel.
This can be used if you have support for the following −
SAP IDT - .unv Universe Introduction
A .unv Universe is created in Universe Designer in SAP Business Objects XI 3 or Universe created using Universe Design tool. It can be converted to unx file in Information Design tool.
Following SAP Business Objects version can create unv files −
Universe Design Tool (UDT)
Universe Design Tool Desktop Edition
Universe created using UDT is stored with a file name .unv in the local folder or in the central repository
To use .unv Universes in IDT, you first need to convert them. You can convert the following unv Universes in Information Design Tool −
Converting .unv Universe in a Repository
Universe file .unv to be converted should be stored in the repository. If the Universe is created with a Design tool earlier than SAP BusinessObjects 4.0, then you should upgrade the Universe using Upgrade management tool.
To convert a Universe in IDT, go to File − Convert.
In the next window, you have to select unv file from the repository to convert to unx file. Enter the Repository username and password to connect.
Select Universe from the repository that you want to convert. Click OK.
Select the Destination Repository folder → Browse to select a folder in the repository where you want to save .unx Universe. To create named parameters for prompt, select the checkbox as shown in the following screenshot.
Save for all users’ option allow all users to open the Universe without entering the Repository password. Click OK to start conversion.
Once you click OK, conversion starts, and you get the following confirmation message.
Converting .unv Universe Locally
To convert a Universe in IDT, go to File → Convert.
In the next window, you have to select .unv file from the local folder.

SAP IDT - Dealing With Published Universes
You can retrieve a published Universe from the local file system or from the Repository. To retrieve a Universe from the local file system, you need a local projects view where business layers and referenced resources are saved. In local projects view, right-click project folder, go to Retrieve Universe → from a Local Folder.
Select the Universe you want to retrieve and click Finish.
Retrieving a Universe from a Repository
To retrieve a Universe from the local file system, you need a local projects view where business layers and referenced resources are saved. You can retrieve a Universe from a Repository in two ways −
Method 1
Right-click Local Project folder → Retrieve Universe → From a Repository.
Enter Repository password and click Connect.
Select the Universe from available folders in Repository and click Finish.
Method 2
Another way is by going to the Repository Resources section and select the Universe you want to retrieve.
Select a Local Project for retrieval and click OK.
To remove the local security requirement, select the “Save for all users” option when selecting the Universe in the repository.
SAP IDT - Projects
To design a Universe in IDT, the first step is to create a project in Local Project views. All the resources like Data Foundation and Business layers are managed in a project. You can navigate to local projects and access the resources in the local project using Information Design Tool (IDT).
Once you create a Local Project, resources can be populated under it in different ways −
- You can create new resources using “New” option.
- Convert .unv Universe created from Universe Design Tool.
- Retrieve a published Universe.
- To edit a resource, you can double-click on a resource under Local Project.
Checking Existing Projects in IDT
You can open an existing project in IDT. Go to File → Open Project.
A new window will open. You can select from the root directory or from archive file to import an existing project.
To import from the root directory, click on Browse, select the Project you want to import and click OK.
Creating a New Local Project in IDT
To create a new project in IDT, go to File → New → Project.
Enter Project Name, location and click Finish.
The project is created under Local Projects views.
Editing an Existing Project
You can also edit an existing project. Open an existing project by going to File → Open Project. You can also open an existing Universe under any Local Project area.
Once you open an existing project, you can go to each object by double clicking the object name under Local Project folder.
Make changes as required and click the Save button.
Deleting a Project in IDT
To delete an existing project, right-click on the project under Local Project area.
To delete a project permanently, you can select “Delete project contents on disk option” in the "Confirm Project Delete" dialog box.
If you select this option, the deletion is permanent and cannot be undone. Click on “Yes” to confirm the deletion.
If you did not delete the project contents permanently, you can open the project to make it available.
Project Synchronization
Project synchronization deals with comparing resources in local project views with an associated shared project in the repository. Using project synchronization, you can detect add/delete resources, difference between resources. Based on differences, the local project view and shared resources can be updated.
Under Project synchronization, there are two different panes −
Shared Project Pane
It lists the resources in shared project on the server. If there is a lock icon in the form of resource, it means the resource is locked. Synchronization status lists the status of each resource by comparing resources in shared and local project views.
Different Synchronization Status
Added Locally − A resource is added in the local project but not in the shared project.
Changed Locally − A resource was changed in the local project but not in the shared project.
Deleted Locally − A resource was deleted in the local project but still exists in the shared project.
Added on server − A resource is not in the local project but exists in the shared project.
Changed on server − A resource was changed in the shared project but not in the local project.
Deleted on server − resource exists in the local project but was deleted in the shared project.
Synchronize − Both resources are identical.
List of Resources in Synchronization Status Pane

How to Perform Project Synchronization?
To perform Project Synchronization, go to Windows → Project Synchronization.
Click ‘Change session’ to open a session on the repository system where the shared projects are saved.
Select a project to synchronize in the shared project list.
Locking a Resource
To lock a resource in Project Synchronization, it should be under shared project. Lock informs other developers that you are working on the resource.
To lock a resource − Select the shared project from shared project list. Expand the project. Select the resource → Right click → Click Lock.
Unlocking a Resource
To unlock a resource, select the resource under Project Synchronization. Right click → Unlock.
Saving Resources in IDT
It is also possible to save any resource in a local project as a report in the local file. To save a resource, right-click on any resource, Save As.
In the Report Location box, enter a file path, file name, and file type for the report. The file type can be .pdf, .html, or .txt.
To browse the local file system to find a file path, click the browse button.
For larger resources (data foundations and business layers), you can select which metadata elements to include in the report in the Metadata Elements box.
Click Generate to create the report.
SAP IDT - Managing Connections
A connection in IDT is used to connect to a relational or an OLAP data source using SAP BusinessObjects reporting tool. It can be a local connection or a connection published in a central repository.
Different Types of Connections Supported in IDT
Following are the types of connections that are supported in IDT −
Relational Connection
This is used to design Data Foundation layer in Information Design tool. You can import tables and joins from data source.
OLAP Connection
Using an OLAP connection, you can design a business layer while creating a Universe. It allows you to connect to multidimensional schema directly and to import them for Universe design. Later, they can be used with SAP Business Objects reporting tool.
BICS Client
To connect to SAP NetWeaver BW, you can use SAP BICS client middleware to provide access to BEx query. Connections in IDT can be locally saved or they can be secured and published in a central repository.
Local connections are saved as .cnx files and they can be accessed by any user who is running IDT. Once you publish the connection to the repository, they are changed to a secured connection.
A secured connection is published into the repository and saved in Connection folder. You can also create secured connections by using Insert Relational and Insert OLAP connection commands from the repository resource view.
Following are the key properties of a secured connection −
Users must be authenticated.
User rights can be defined at the user level to grant or deny access to connections or connection properties.
Secured connections can be used or shared by authenticated users.
Creating a New Connection in IDT – Relational
Go to Information Design tool under BI client. To create a new Relational connection, first start with a new project under Local Project view.
Click New → Project → Enter the Project Name → Finish.
Right-click on Project name → New → Relational Connection.

Enter the Authentication mode, user name and password. Enter the host name and the Instance number and click Next.
In the next window, you can define connection parameters like - Time out, Array fetch size, Array Bind size, etc. Click Finish.
A Relational connection to source database is created with .cnx file extension. You can click Test Connection.
Lower part of Window tells you about connection parameters - Login parameters, configuration parameters, etc.
→ Test Connection → Successful
Similarly, you can create a Relational connection for other data sources.
We have to publish this connection to the Repository to make it available for use.
Right Click on connection name → Publish connection to Repository → Enter BO repository password → Connect → Finish → Yes.
.cns- secured Repository connection
.cnx-local unsecured - If you use this connection it will not allow you to publish anything to the repository.
This shows how a relational connection can be created in the Information Design Tool. To summarize the steps that are involved in creating a connection −
- Enter the name of the connection
- Select the middleware for the target database
- Enter the login parameters to connect to the relational data source
- Configure and customize parameters to optimize the connection and Finish
- To change it to secure, publish the connection to the Repository
Renaming or Deleting a Connection
To rename or delete a connection, right-click on connection name under Local Projects area.
You can also delete or edit a Relational connection like this.
Creating a New Connection in IDT – OLAP
An OLAP connection is used to connect to multidimensional view or a data model to design Business Layer in Information Design tool.
To create a new OLAP connection, right-click on Project name → New → OLAP Connection.
Enter the connection name, description and click Next.
Next, select an OLAP middleware driver. It shows a list of all available OLAP data sources. You can select any of OLAP data source as per requirement.
Note that you don’t need to create a Data Foundation, as an OLAP directly hits the Business Layer. You can define dimensions and measures and other properties at Business Layer.
Select the suitable middleware driver to connect to OLAP data source and click Next.
Enter the connection parameters, authentication details, system name, instance number, etc. and click Next.
You can also select a specific cube to connect or all the cubes in the design time repository. If you select a particular cube, then using this OLAP connection you can design Business Layer only on the objects available in that cube.
Click Finish.
Now, you need to publish the connection to the Repository. Right-click on connection → Publish the Connection to the Repository.
Login Parameters for Connection
When you create a relational or an OLAP connection in IDT to connect to any data source, you have to provide login parameters of source database such as Host Name and Instance Number.
Connection Parameters
While creating a connection, you can configure various connection parameters −
Connection Pool Mode − This is used to keep the connection active.
Pool Timeout − When you set the connection pool mode to keep connection active for, length of time in minutes to keep connection open.
Array Fetch Size − This tells the maximum number of rows that can be fetched from the database.
Example − Suppose you enter a value of 25 and you query returns 150 rows so it will be fetched with 6 fetches of 25 rows each.
Array Bind Size − This field is not required for designing Universe in IDT.
Login Timeout − It determines the minutes a connection attempts timeout and an error message is displayed.
There are various custom parameters that can also be defined like ConnectInit, Hint.

SAP IDT - Data Foundation Layer
A Data Foundation contains one or more tables and joins from one or more relational databases that forms the design of Business Layer. A relational connection is used to design Data Foundation layer. You can add various other objects at Data Foundation that enhances the capabilities like - Derived tables, custom calculations, context, LOVs, etc.
It is also possible to design multiple Business Layers on a single Data Foundation thus allowing you to build multiple Universes on single Data Foundation Layer.
Types of Data Foundation
In Information Design Tool, you can build Data Foundation that is – Single-source enabled or multi-source enabled.
Single-source Data Foundation supports a single Relational connection. Single Source Data Foundation supports a local or a secured connection so the Universe designed on this can be maintained locally or can be published to the Repository.
Multi-source enabled Data Foundation supports one or more relational connections. Connections can be added when you design the Data Foundation or can be added later. Multi-source enabled Data Foundation is designed on secured connections published in a Repository.
Data Foundation Editor
A Data Foundation editor is divided into multiple panes −
- View Pane
- Properties Pane
- Browsing pane
The Data Foundation view pane contains tables and joins. Master contains tables and joins that are connected with each other in a logical manner.
Properties pane defines properties of each object. To check the properties, you have to select any object in the Master tab.
Using the browsing pane, you can work on different elements in data foundation like connections, Data Foundation, Aliases and Contexts, LOVs and parameters.
You can also perform a search in Data Foundation. To perform a search, click the 
icon.

Defining Table Keys
There are two types of keys in a table in Data Foundation layer −
Primary Key − Unique and only one primary key in a table.
Foreign Key − It is used to match a unique value in other table.
To define a key, go to Data Foundation Editor. Select Table → Click Detect → Detect Key.
You can also define a column as primary key or foreign key by selecting the particular column in a table → Right-click → Set as Key → Primary/Foreign Key.
SAP IDT - Joins In Data Foundation
Joins are used to combine tables in Data Foundation. It defines how data is queried in the tables. Joins are defined when you link one column of a table to other column. It is possible to insert Joins manually or to insert automatically by clicking on Detect Join option.
To insert a new Join, go to Insert → Insert Join.
Select Table 1 from the dropdown, Table 2 from the dropdown from all the tables in Data Foundation. Select columns from Table 1 and Table 2 to join. Select the type of Join you want to insert → OK.
Editing an Existing Join
To edit an existing Join, double-click on Join and it will open Edit Join editor as above.
Derived Tables
A derived table is a virtual table in the data foundation that combines other tables using calculations and functions.
You can use derived tables for the following purposes −
To create a table with columns from other tables. The column definitions can include complex calculations and functions.
To create a single table that combines two or more tables.
To create a table that contains a selection of columns from different tables.
To Insert Derived table, select table header → right click → insert → derived table.
Enter the Unique name and click OK.
Table Alias
An Alias table is known as reference to a standard table in Data Foundation. The data in Alias table is completely same as the original table.
Alias tables are used to break loops in Join path in Data Foundation layer. An Alias table can also be used to rename a table.
Insert an Alias
To create an Alias table, select the table on which Alias has to be created. Right-click the table header → Insert → Alias table. To create an Alias table on more than one table, use CTRL key to select multiple tables.
Alias is used to break any loop and to handle Fan trap and Chasm trap issues.
Detect an Alias
To detect an Alias, go to Detect under Data Foundation layer.
To detect a table alias, the following condition should be met.
Contexts
Contexts are also used to break the loops in Data Foundation when you are not able to break the loop using an Alias table.
When you have multiple fact tables that are connected to a single dimension table, you create a Context for each fact table in this case.
In a context, there are three states defined for a Join −
Included Joins − In a part of the schema that is ambiguous, the context solves the loop by defining a path with the included joins.
Excluded Joins − In a part of the schema that is ambiguous, the excluded joins define the path that context will never take.
Neutral Joins − They are in a part of the schema that is not ambiguous, and are always included in the query path of the context. Any join that is not explicitly included or excluded is neutral.
A Context can be defined manually or by clicking detect Context option.
To detect Context → Open the data foundation editor by double-clicking the data foundation name in the Local Projects View.
From the Aliases and Contexts pane, select the Detect Contexts icon.
The command analyzes the join paths and proposes contexts to resolve any loops that cannot be resolved by alias tables.
Next, open Detect Contexts dialog box, select the contexts you want to insert.
To see the context highlighted in the data foundation view, click the proposed context name. A join that is included in the context is shown by an included icon 
A join that is excluded is shown by the excluded icon 
. Click OK to insert the selected contexts into the data foundation.
SAP IDT - Business Layer
Business Layer in IDT consists of metadata objects like dimensions, measures, attributes, and filter conditions. Business layer can be designed on the top of Data Foundation layer or can be created directly on an Info cube or on a Modeling view in HANA.
When you design a Business Layer, it can be published to the repository or to a local folder. Business layer is used to manage metadata objects before it is published to BI repository.
An Object in Business Layer can have the following three states −
Active − This is default state of an object and objects are available in the query panel.
Hidden − These objects are valid but are hidden in the query panel.
Deprecated − These objects are not valid and hidden.
You can create different type of objects in Business Layer −
Dimension − Dimension represents contextual information in Business layer.
Measure − Measure represents the factual data on which we perform the analysis. These are numerical values where you perform aggregations and calculations.
Attribute − Attribute is defined as an object which is associated with another object to provide more information about the object.
Filter − Filters are used to limit the data that are returned in the query. You can define business filters on dimensions and measures by creating and combining conditions.
While using an OLAP data source, you can find the following objects −
- Hierarchy
- Level
- Named Set
- Calculated member

Queries in Business Layer
A Query panel is used to create queries and query objects are associated with the Business Layer. These are normally used in IDT to validate the Business layer.
Inserting and Editing a Query
To insert a new query or edit an existing query, click the Query pane in the Business Layer pane.
Click Insert Query to add a new query. This will open the Query panel. You can create a new query or edit an existing query and click OK. Select the objects in Query panel → OK.
Enter the name and description of Query. You can edit the objects in query by clicking Edit query option. To execute the query → Execute Query.
Aggregate Awareness
Using aggregate awareness, you can use pre-aggregated data in tables in the database. It is used to improve query performance by processing less number of rows.
When you add an aggregate aware object in query, the query generator retrieves the data from the table with the highest aggregation level.
For example − Consider a Sales Fact table where sales is aggregated by per month. If your query asks for sales per month, the query generator will retrieve the data from aggregated table.
Setting Up Aggregate Awareness
To use aggregate awareness, first the aggregated table has to be loaded to database and then add the table to Data Foundation.
Define aggregate aware objects. These are the objects in the business layer for which you want queries to use the aggregate tables when possible, instead of performing aggregation using non-aggregate tables.
In the SQL expression for the object, define the SELECT statement to use the @Aggregate_Aware function −
@Aggregate_Aware(sum(aggr_table_1), …, sum(aggr_table_n))
Select the object in Business Layer → go to SQL Assistant → under Functions → Aggregate Awareness.
SAP IDT - Building Query In Query Panel
You can use the query panel to create or preview queries on a Business Layer or on top of Universe published in the repository. The query panel allows you to add objects in the query and to preview the query results. A query panel can be opened using the following methods −
Go to Queries → Insert Query.
To select the objects that you want to include in the query, drag objects from the business layer on the right into the Result Objects pane.
For hierarchy result objects, select members to include or exclude in the results. To open the MemberSelector, click the arrow to the right of the hierarchy object name 
.
To filter the results of the query, drag objects from the business layer into the Filter Objects pane.
Selecting Named Sets
Named set are defined in Business layer while creating Universe. To select members by named set, your hierarchy should define minimum one named set.
Named sets are displayed when you click on metadata under the member selector. If you can’t find a named set folder under metadata, it means the hierarchy has no named set.
Selecting Calculated Measures
You can also use calculated measures with hierarchy but hierarchy should have minimum one metadata defined. They are defined in Business layer.
Like named sets, calculated measures are also displayed when you click on metadata under member selectors.
SAP IDT - Dependency Among Resources
In a Universe there can be many objects which are dependent on each other and moving, deleting a resource can impact other resources that depends on that resource.
To check the dependency between different resources, you can select show local dependency. When you select a resource, it displays two tabs - dependent and referenced resources.
The Dependent Resources tab lists resources in the same local project that depend on the selected resource. The Referenced Resources tab lists the resources in the same local project that are referenced by the selected resource.
If you want to check the resources that will be impacted when you change the Data Foundation, you can right-click → Show Local Dependency.
