• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT055 - Namespaces not allowed in external name of service ?

  The SAP error message /IWBEP/CM_MGW_RT055 Namespaces not allowed in external name of service typically occurs in the context of SAP Gateway services, particularly when defining or consuming OData services. This error indicates that there is an issue with the naming convention used for the external name of the service, specifically regarding the use of namespaces.
  Cause:
  The error is caused by the inclusion of a namespace in the external name of the OData service. In SAP Gateway, the external name of a service should not contain any namespace prefixes. The external name is meant to be a simple identifier that does not include any hierarchical structure.
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check the Service Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Open the service definition that is causing the error.
  
  
  
  Modify the External Name:
  
  Locate the external name of the service. This is usually found in the service definition properties.
  Remove any namespace prefixes from the external name. The external name should be a simple string without any slashes or dots (e.g., MyService instead of namespace/MyService).
  
  
  
  Regenerate the Service:
  
  After making the changes, regenerate the service by right-clicking on the service and selecting "Generate".
  Ensure that the service is activated after regeneration.
  
  
  
  Test the Service:
  
  Use the transaction /IWFND/MAINT_SERVICE to check if the service is properly registered and activated.
  Test the service using the OData service URL to ensure that it is functioning correctly.
  
  
  
  Related Information:
  
  Namespaces in SAP Gateway: In SAP Gateway, namespaces are typically used for defining the structure of the service and its entities. However, they should not be included in the external name of the service.

  SAP Documentation: For more detailed information, refer to the official SAP documentation on SAP Gateway and OData services, which provides guidelines on naming conventions and best practices.
