Dear SAP experts,
In standard SAP, users can change batch number when do GR against an outbound delivery. Now we want to prevent this but it seems that theres no control in customizing.
The solution were thinking about is either making the filed as display only or let the system pop up an error message if the user tries to change the batch number.
The question is can these be done with user exit MB_CF01(updating of material document data upon posting)? Can anybody shed some light? Any input is highly appreciated. Thanks in advance.
