Customer Exit - no ZXRSRU01
I am trying to create a Customer Exit, but for some reason I am not allowed to change anything.
After creating my project in CMOD, i double-click on FUNCTION EXIT_SAPLRRS0_001 and I now want to go into the include ZXRSRU01. I now get a message saying Program names ZX... are reserved for includes of exit function groups.
Do I need to create the function ZXRSRU01 first? It is like this include does not exist. Or have I missed out on something when creating my project in CMOD?
I have activated everything, but still I am not allowed to og into the include ZXRSRU01.
