Perhaps this is a very fundamental question. But I believe the answer from practising persons would be in simple words to understand when comapred to help links on this subject.
Many times answers to my problems in SDN fora end-up with suggestions to use some User-Exit.
How to use these? Does this subject fall into ABAP area OR any common PM authorisation (like mine) will do for using these Exits.
Would be thankful if someone explains in simple terms.
