Public Sector Management (PSM)

Point in time at which an SAP program executes an extension according to the Customizing settings. This extension does not contain any modifications to the SAP standard.

SAP works with two types of business transaction event:

• Process events: Customers or partners implement a program flow that differs from the standard application, and which delivers different return parameters. Process events take over the task previously performed by user exits.

User exits are still included in the system.

• Publish&Subscribe events: Customers or partners either implement an additional function previously not delivered by SAP, or pass data to a linked application. The function does not deliver any return parameters. Publish&Subscribe events take over the task previously performed by customer exits.

Customer exits are still included in the system.

ABAP Objects implement these events as Business Add-Ins (sometimes abbreviated to Add-Ins).
