In order to process an outbound IDoc, I created a Z_function_module as a copy of the standard function module provided by SAP fot the same purpose. I included this Z_function_module in a new Function Group.
The problem is that I need to call, from this new FM, a customer function (a user-exit) that was called by the standard FM, somewhere in the processing. The coding of the ZFM is almost identical with the standard FM, except a few lines added for a specific client request.
While the standard FM calls the Customer function (the user-exit), my Z-FM doesn not. The Customer function is included in a CMOD enhancement project. Activating or deactivating this project has no effect on the functionality.
What should I do, in order to call the user-exit in my Z-FM too?
