Proxy Interface Creation in SAP Backend Metadata Repository

A proxy interface is a generated ABAP artifact that represents an external web service, allowing a developer to call remote service operations as if they were local ABAP method calls. Developers use it to integrate SAP systems with external services by mapping service operations and data types into ABAP-consumable objects. It can also be enhanced with preprocessing logic to manipulate or validate data before it is sent to or received from the remote service.
