This document outlines the process for sub-contracting returned goods that cannot be repaired in-house. The process involves creating a repair order, receiving the returned goods, creating a service order with a sub-contracting operation, generating a purchase requisition, creating a purchase order, sending the goods to an external vendor, receiving the repaired goods back, and completing the repair order. Key steps include setting indicators to enable sub-contracting, adding a sub-contracting operation to the service order, and using transaction codes to send and receive goods from the external vendor.
