Does SAP activate some user exits (enhancements) implicitily?
The situation is:
I'm using the enhancement QQMA0025, which has the user exit EXIT_SAPLIQS0_017. Well, I created code in the user's exit include (ZXWOCU21). Activated the include and the user exit and it executes correctly.
What seems strange to me is that there is no project in CMOD which has the enhancement QQMA0025. So, the user exit should not execute (but it is still executing).
And here comes the question of the subject: "Does SAP activate some user exits (enhancements) implicitily?"
If yes, explain me how to find them and so on.
Thanks a lot in advance.
