I have a question on the authorization user exit for SAP business partner transaction (BP).
My client wants me to develop an user exit for blocking changing of existing SAP business partner.
He wants to make all BP fields the display mode except partner function fields of SD customer master.
Namely, only partner function related fileds are open for changing and all the remaining fields (general view, company code view, purchasing view etc) must not be modifiable for end users after creating that business partner.
Please let me know how I can implement above user exit function for business partner changing.
Thank you for your reply in advance.
