UserExit 'ZXCV001U01' in EXIT_SAPLCV00_001 is not triggered

Hi!

I need a UserExit which is triggered when I save/change documents with transaction CV01N or CV02N and provides me the status and some others fields of the document. I found the exit EXIT_SAPLCV00_001 with the include ZXCV001U01 which would provide all information I need. The problem is that this exit is NOT triggered. I have activated the exit with CMOD but still the exit is not fired. The only exit which is triggered while saving the doc is ' EXIT_SAPLCV110_004' with 'ZXCV110U04' but this exit only provides REFERENCE(PFX_OKCODE) TYPE SY-UCOMM as a parameter.

Which exit works for me and what steps are necessary to use it!

Thanks,

Konrad
