The in-house repair process (scope item 3XK) has specific characteristics:

Advanced Returns Management (ARM) can be used for customer returns: ARM integrates with in-house repair to manage return authorizations and goods receipt.

Items can be added to repair orders using service order templates: Templates streamline adding standard repair items to orders.

Credit checks can be executed in repair orders and repair quotations: Credit management is supported to ensure customer creditworthiness.

For each repair object, a service contract item must be assigned: Contracts are optional, not mandatory for repair objects.

An in-house repair process requires the Service with Advanced Execution scenario: Advanced execution is an enhancement, not a requirement for basic in-house repair.

These align with SAP's in-house repair design.
