New types of internal notes or an explanatory text in PO
Please, tell me, can we create our own types of internal notes or an explanatory text in PO?
Unfortunately again for you: there is no OSS note to downgrade this feature in SRM 4.0.
So you have to develop it by yourself and modify the standard ABAP code.
This is quite simple, so a good SRM ABAPer can do it by modifying function group BBP_PDH_TEXT.
