Now ZVA02 should be allowed to used by only certain type of User group, we tried to put this check in user exit MV45AFZZ, but when i open transaction ZVA02 in debugging mode, i get VA02 value in sy-tcode and not ZVA02,
We can create transaction variants specific to user group too--No requirement of touching at Exits level.
Recently Mr Moazzam helped me on this variant groups in SHD_CHECK.
Follow this thread& links provided by Moazzam-FD32--Some fields need to restricted for some users only..
Hope this helps...
Note: why you created Z transaction that to for Sales order creation--when standard Tcode itself can be tailored here.
