Subcontracting Process In SAP MM

Subcontracting process in sap mm is a kind of special procurement where your company orders material from external vendor and provides components to the said vendor for production.

For example, if your company requires a product FG1112 , then for the production of the said product i.e. FG1112, company provide two raw materials RM11 and RM12 respectively to external vendor.

After production or rework your vendor will supply required material i.e. FG1112.

  4. In case of over or under consumption of the components provided to vendor, subsequent adjustment entry has to be made.

For  providing material to Vendor available stock types are unrestricted use and quality inspection i.e. we can supply material to the vendor from these stocks only.

A material can be provided to the vendor through Transfer Posting from unrestricted use stock to the stock of material provided to the vendor with a movement type 541 O.
