I have a requirement to modify standard sap screen for transaction PR05 in travel module. I need to add a few fields to the screen and hide a current field. Can you guide me the best way to do it.
I think of the following ways:-
1. Change the config for the screen (but I guess by this way I cannot add new field, just hide one of the current field)
2. Find user exits ( can I use them to modify screen or can just run them at certain events)
3. changing standard code
thanks for your assistance.
