[Stephen_Zhou]

Hi Guys: We use MD51 for project planning scenrio, it works without MRP area, but if we activate MRP area, the requirement doesn't work in MD51.

Hello

Check the information below from note 550844:

3. Can I use the make-to-order production or engineer-to-order planning strategies in MRP areas?
Answer:
The strategies of the make-to-order planning can be used only in the plant MRP area. Therefore, individual customer segments are always in the plant MRP area even if a storage location that refers to a storage location MRP area is assigned in the sales order. You cannot plan individual customer segments in the MRP area.
As of SAP Enhancement Package 3 for SAP ERP 6.0, you can use the business function OPS_PS_CI_1 in the project system to achieve a work breakdown structure (WBS) account assignment on MRP area level. Restriction: Note that to procure project account-assigned requirements from MRP, you can only create purchase requisitions or stock transfer requisitions. For technical reasons, you cannot use stock transfer reservations for the procurement.
