Assign COPA Char Group to PR/PO screen
I want to assign COPA screen to appear during PR/PO creation. I have assigned the business transaction RMBA, RMBE & RMBL in the 'assignment of char group for assg screen' (KE4G). But, still during PR/PO creation, the COPA screen does not appear in it.
Is there something that I must do before this changes take effect?
