Debugging CIF inbound processing User Exit

Hi,

I'm currently working on user-exit APOCF001 (Inbound processing: Location), and I have some problem (simply put, my user-exit doesn't work and I don't know why 🤪). The data tranfer from the source R/3 system to the destination APO system is triggered from this source R/3 system, while the user-exit is executed in the APO system.

Is there any way to debug this user-exit? I've tried setting up break points, with no success. I have thought of writing to a file in the user-exit, but I'd prefer use this solution as a last resort.

Thanks for your reading, thinking and/or answering!
