User defined functionality included to predefined SAP standards. Point in an SAP program where a customer's own program can be called. In contrast to customer exits, user exits allow developers to access and modify program components and data objects in the standard system.
On upgrade, each user exit must be checked to ensure that it conforms to the standard system.
There are two types of user exit:
User exits that use INCLUDEs.
