Hi all,
I need to disable input for the EPSTP field (a standard one) in all the Purchase requisition's transactions (me51n, me52n, me53n).
I should make it not editable (disabling it, or turning it to gray) when the purchase req. meets some requirements; I should control these conditions in a user exit, and there write the code to disable the field in order to make it not editable (keeping the value it has).
Can anyone please guide me to this procedure? Thanks in advance.
Matteo
