Further notes

User exits, in contrast to modifications, are not affected by SAP releases because they are not written in SAP original code but in a name area that is reserved for customers.

The general procedure for creating user exits is described in the user exit transaction under the menu path “Utilities – Online manual”.

Each user exit is documented.  You will find the documentation by pressing the pushbutton “SAP doc.” in the user exit transaction.
