Error Message: Backend Services are already registered for System Alias '&1'
Summary
This error indicates that you are trying to register backend OData services for a system alias that already has services registered. Essentially, the system prevents duplicate registrations of backend services for the same system alias.
Root Causes
- Attempting to register the same backend service multiple times for the same system alias in the SAP Gateway system.
- Incomplete or inconsistent cleanup of previously registered services, leaving stale entries in the service registration.
- Misunderstanding of the system alias concept, leading to multiple registrations for the same alias instead of creating or using distinct aliases.
- Transport or system copy activities that duplicate service registrations without proper adjustment.
