Hello.
Im a SD consultant and my requirement is that in VF02/VF03 upon entering a billing doc number and entering the doc itself there should be pop up messege that says '' billing document has been cancelled'' that is of course if it really is. I know how to code it but i cant find the right exit in SAPMV60A to do so .Im not familiar with badi either so im in a bit of a spot.I was wondering if any of you fine experts could help me?
