Hi,

Could you please describe what the purpose of validation? One posible solution, is to use a Field Exit for field RSNUM. You can create a Field Exit in transacción CMOD, in the transaction field enter de code =prfb.

Here is an explanation created by Sandra Rossi.

Did you try to find an enhancement or BAdI call in the PAI modules/forms either implicit as start/end of forms like beleg_lesen or explicit like beleg_lesen_01 of es_sapmm07r (As I suggested in previous scn/thread 'How to Restrict user mb22 when user click on PRINT PREVIEW')
