Hi,
I was required to add validation for Material Group 3 (VBAP-MVGR3) in 'Additional Data A' tab (VA01/VA02). The corresponding screen number in 4459. In the PAI section, there is a module called 'vbap_bearbeiten'. In this module, there is an enhancement point called 'VBAP_BEARBEITEN_10 '. I created an implementation of this enhancement point to call a validation subroutine which i put in user exit MV45AFZZ. My problem is whenever a wrong entry is entered for that field, the whole screen in the 'Additional Data A' tab turned grey and disabled for user entry. Re-entry for the correct Material Group 3 is not allowed.
Initially, i used a different approach. I made a core change to screen 4459 by adding a statement like below in the PAI section :-
FIELD vbap-mvgr3 MODULE zsd_check_mvgr3 ON REQUEST.
In fact, the validation worked without any issue. User was prompted for an error message and then was allowed to re-enter a correct entry for that field if a wrong entry was entered initially. However, since this approach involved a core change, it was not allowed by my superior and he demands for using the enhancement framework approach.
Kindly please let me know if you have any idea of resolving this issue. Thanks much in advance.
