Stock Transfer of Components to be Provided 
Use
You can procure the components that you provide to a subcontractor for the production of an assembly, by transferring stock from a plant to the MRP area of the subcontractor.
Prerequisites
- You have created an MRP area for the subcontractor X in Customizing and have entered the vendor number of the subcontractor there.
- You have assigned the components to be provided to the MRP area for the subcontractor X by creating an MRP area segment in the material master record of the components to be provided.
- You have entered a special procurement key for Stock Transfer from Plant to MRP Area in the MRP area segment.
- You have entered the special procurement key for subcontracting in the material master of the assembly that the subcontractor produces.
- You have created a source list entry for the assembly that the subcontractor produces. In this, you have entered the subcontractor as a fixed vendor and have set the indicator 1 for relevant to MRP in the MRP field (see also Determining Source of Supply for External Procurement).
Features
During the planning run, the system determines the subcontractor X as the vendor for the assembly using the source list and creates a purchase requisition for the assembly.
The BOM of the assembly is then exploded. The dependent requirements of the components to be provided are assigned to the MRP area of the subcontractor X.
Due to the special procurement key in the MRP area segment of the components to be provided, the system determines that the components are to be procured by means of stock transfer from the plant to the MRP area. A stock transfer reservation is created in this situation. This type of reservation is the movement type 541.
Using the evaluation SC Stock Monitoring for Vendor (transaction ME2O), you can display the reservations of the components to be provided and post the goods movement.
