PO_CONFIRMATION_DELETE Validation Profile active

Hello SNC Expert ,

We have active the validation Profile # PO_CONFIRMATION_DELETE so that

any changes like qty , price and dates will remove the confirmation

from SNC , Which supplier has to go and confirm again in SNC.

We want only activate this validation on Quantity changes , Is there

any validation profile exit in std process where if there any qty

changes in the PO then only delete the confirmation not for price or

dates .Or any BADI we can implement to achieve this above functionality.

With Regards

Mahesh
