Hallo
I am trying to preallocte vbak-vbeln in VA01. I do it in Include MV45AFZZ and in FORM USEREXIT_FIELD_MODIFICATION. It is functioning good. The numbers appers in VA01. It saves it also without any error. But when I look for the number in Vbak, it is not save in vbak.
Can somebody tell me In which USEREXIT I have to place my code. so that the vbak-vbeln is filled in VA01.
regards
Waseem.
