I am working on enhancing the CV01N transaction to add a custom tab (and screen) under object links tab. Thru config, we created a tab, but where do I build a screen for that tab? I am looking at the BADI 'DOCUMENT_OBJ' , but couldn't figure out if I can build a screen using this BADI. Have anybody worked on this stuff before? Any screen exits for this task? How does a screen exit BADI work?
Any kind of help would be really appreciated.
