Definition – Subcontracting
- Subcontracting process in SAP MM is a special procurement process where a manufacturer outsources the whole manufacturing process or a part of it by sending the components of a machine or assembly to its supplier
- The supplier builds/ assemble the machine with components and returns the final product to the manufacturer
- The supplier charges for the services which it has performed to build or assemble the final product
- Generally we send the raw material components to the supplier and receive the semi-finished material as the final product

So they will take help from a subcontractor to do the assembling job. The bicycle manufacturer can send the components (or parts) of the bicycle to the supplier (or subcontractor). The supplier will do the necessary assembling and return the bicycle (final product). Below is the list of bicycle components which a manufacturer can provide to a subcontractor for assembling.

Fiori Apps to run Subcontracting Process
- Create Subcontracting Purchase Rerquisition manually: We can create a subcontracting PR with item category ‘L‘ using a Fiori App “Process Purchase Requisition“. Please note that this Fiori App was formerly known as “Manage Purchase Requisitions”.
- Subcontracting Purchase Requisition created by MRP: Purchase requisition can also be created automatically through MRP by using Fiori App “Schedule MRP run“.

- Purchase order can also be created directly with item category ‘L’ using FIori App “Manage Purchase Orders” or “Create Purchase order”.
- Transfer Posting: In this step we can post goods issue to transfer BoM components to subcontractor. We can do it by using FIori App “Subcontracting Cockpit“. Earlier this step was known as Post goods issue step.
- Receive Final material from subcontractor: Once the assembling work is completed we can receive the final material in our plant by posting a goods receipt with reference to the Purchase order. We can use Fiori App “Post Goods receipt for Purchasing Document“. Once posting is done the BoM component stock reduces and final product stock increases.
- Create Supplier Invoice: We can post invoice receipt using Fiori App “Create Supplier Invoice“. First simulate an then make the actual posting.
