Purpose
During production, you may want certain operations in a routing to be processed externally by another contractor. In such cases, the system can create a purchase requisition for such an operation automatically on the basis of a production order. Your purchasing department converts these purchase requisitions into purchase orders. When a goods receipt is received for a purchase order, the system automatically creates an inspection lot so you can inspect the externally-processed goods.
Prerequisites
To activate the functions for external processing in QM:

If you want to process more than one operation externally, you can specify different inspection types for each operation.
Process Flow

If necessary, you can still change the inspection type for the goods receipt for external processing in the production order.

The MM component initially uses the material key "0" for the operations that will be processed externally.

The inspection lot is not stock relevant.
