• What is the cause and solution for SAP error message /IWBEP/CM_V4H_COS013 - Service alias '&1' is not unique in service group ?

  The SAP error message /IWBEP/CM_V4H_COS013 indicates that there is a conflict with the service alias in the service group. Specifically, it means that the service alias you are trying to use is not unique within the specified service group. This can occur in the context of OData services in SAP Gateway.
  Cause:
  
  Duplicate Service Aliases: The most common cause of this error is that there are multiple services defined with the same alias within the same service group.
  Incorrect Configuration: There may be a misconfiguration in the service registration or the service group setup.
  Transport Issues: If you have transported objects from one system to another, there might be conflicts due to existing services.
  
  Solution:
  
  
  Check Service Aliases:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Open the relevant service group and check the list of service aliases.
  Ensure that each service alias is unique. If you find duplicates, you will need to rename or remove the conflicting service alias.
  
  
  
  Modify Service Group:
  
  If you have multiple services that need to use the same alias, consider consolidating them or creating a new unique alias for one of the services.
  
  
  
  Re-register Services:
  
  If you have made changes to the service aliases, you may need to re-register the services. You can do this using transaction code /IWFND/MAINT_SERVICE.
  Remove the conflicting service and re-add it with the correct alias.
  
  
  
  Check Transport Requests:
  
  If the issue arose after a transport, check the transport requests to ensure that they did not introduce duplicate service aliases.
  
  
  
  Clear Cache:
  
  Sometimes, clearing the cache can help resolve issues related to service registration. You can do this using transaction code /IWFND/CACHE_CLEANUP.
