Restrict planned orders conversion according to procurement type
We would like to be able to limit the possibilities offered in MD04 for planned order conversion according to the procurement type defined for the material.
For example for a material produced in-house (procurement type E), we would like have a button only for "Production order" or "Partial production order". Currently I have those two buttons, but also process order, partial process order and purchase requisition.
I suppose somewhere in customizing we can change that, but I can't find where.
Can anybody assist me?
