Planning Components to be Provided 

Use

The net requirements calculation for components to be provided in subcontracting takes into account that the provision stock can only be used to cover the corresponding requirement of material provided. The provision stock that is already available from a subcontractor (vendor) can only therefore be used to cover the requirements of material provided at this subcontractor.

The system uses only the stock that has not been assigned to a subcontractor as unrestricted-use stock to cover all requirements.

Integration

If you carry out MRP with MRP areas, you can define an MRP area for each individual subcontractor and thus plan the components to be provided separately for each subcontractor (see Planning for Components to be Provided in Subcontracting, Example for Planning with MRP Areas).

Features

Subcontractor Segments

The system displays the provision stocks and requirements in additional segments for subcontracting in the MRP list or stock/requirements list. A separate planning segment is created for each subcontractor (vendor) for which stocks or requirements for material provided exist.

The system displays the provision stock and requirements of material provided (MRP element SubReq) for a subcontractor in the segment for subcontracting. This display only serves for information, as the actual planning only takes place in the net requirements segment.

The system displays requirements for material provided for a subcontractor without existing provision stock in the segment for subcontracting and displays and plans the requirements in the net requirements segment.

The system also includes subcontracting third party orders and subcontracting third party requisitions in the subcontracting segment.

Planning in the Net Requirements Segment

In the net requirements segment, the system calculates the difference between stock already provided and requirements for material provided.

The system does not include requirements of materials provided by a subcontractor (vendor) that are already covered by existing stocks at the subcontractor's plant in the net requirements calculation. The system therefore does not display these requirements in the net requirements segment.

The system displays and plans requirements for material provided that are not covered by provision stocks in the net requirements segment. You can display the total requirement quantity and the open quantity still to be provided for a requirement of material provided (SubReq) by double-clicking on the requirement of material provided.

Manually Processing Components to be Provided

If you change the planned order or the purchase requisition of the finished product manually, these changes are automatically transferred to the components to be provided. The dependent requirements of the components to be provided are adjusted. You can also change or delete the dependent requirements manually.

Further Processing Options in Inventory Management

In Inventory Management, you must post the transfer posting of unrestricted-use stock to the provision stock of the subcontractor (stock with vendor) for the material components. This posting is independent from a purchase order.

The subcontractor dependent requirements for the components are not changed by this transfer posting.

The system only reduces the provision stock of the subcontractor for the components and reduces the subcontractor dependent requirements for the components once the goods receipt for the product has been posted.

During a partial goods receipt, the subcontractor dependent requirements are reduced proportionally.

You can find further information on subcontracting in the SAP document MM – Inventory Management under Subcontracting.
