I have created reservations manually against cost centers and projects(wbs elements) in MB21. I am wondering how or if it is even possible to create purchase requisitions or purchase orders related to these reservations? I am familiar with these on pm orders but my knowledge of manual reservations and this business logic is minimal.
I need to know if that is possible or even makes sense as I will select banfn and ebeln from resb based on reservation and select further data if it is.
