Changing Batch Characteritics - MSC2N - EXIT_SAPLCLFM_002
when the characteritics are changed via transaction MSC2N and the user chooses to save, I'm aware of the three user exits that are processed but I'm not sure which one I need to use.
I want to perform an authority check to make sure who ever is making the changes is actually authorised to do so. If the authority check fails is there a field/table I can modify in any of the three user exits that will force the system not to save, and also maybe stay on the current tab screen, i.e. Characteritics tab.
Hope someone can help, thanks, C.
