I have a requirement for XK02
after a vendor is created it is created with a certain account group .
when the account group = INT then with XK02 the user may not be able to change the adress anymore
when the account group = EXT then with XD02 the user may change the adress
we only have an authorization object F_KNA1_GEN for the adress where we can only enter if a user may change or view.
I tried with shd0 to create a transaction variant but since the account group is nowhere on the screen I can't fix the value to that or allow only vendors of a certain account group to be selected.
how can I make this requirment ? do I need to use user exits or are there other options to expand the authorization object F_KNA1_GEN with the account group ??
