Corrective Maintenance & Preventive Maintenance
In Preventive Maintenance, routine checks are performed according to the company’s maintenance strategy to ensure that machines are running as per the required parameters. In SAP PM, using routine maintenance plans you can create a preventive work order.
In Corrective Maintenance, you correct a malfunction or a machine failure by raising a notification in the system. The work order is received by the technician who enters the information. An authorized person in the PM system approves and completes the work as per the work order.
In certain scenarios, a corrective work order is created as a result of preventive work order. When a routine checkup is performed, the technician finds a failure or a malfunction in the operating machine and a corrective work order is created to clear the fault.
Note − In SAP system, PM01 is the order type to perform Corrective maintenance and PM03 is to perform Preventive maintenance.
