Hi,
During document posting via FB01/F-02, I need to validate characteristic in profit segment. Currently I'm using user exit ZXKNTU02, It is working fine. But I heard that it is not good to use that user exit as some standard tcode is also triggering that user exit.
I looked at user exit ZXKKEU05 but this one is getting triggered during PBO, this is not good because I need to issue an error message if the validation fails...
