SAP Universe Designer - Creating Schemas

A graphical representation of tables and joins organized to create a database structure is known as schema.

• Setting up table joins and cardinalities
• Fixing join issues: loops, chasm traps, and fan traps
• Performing integrating test of schema

You can select different join types and cardinalities based on data in both tables. You can also click on detect button to select cardinalities automatically.
