i just want to control table maintenance generator (SM30) for Z-table,at the run time for the duplicate for KUNNR and LIFNR.
KUNNR = A and LIFNR = B.
Again if i enter KUNNR = A and LIFNR = B.
and KUNNR = A and LIFNR = B.
for both condition it will show the error message .
Particular one vendor(LIFNR) will be used only for one customer(KUNNR).
thanks and regards
