  The SAP error message /IWFND/CM_V4_COS131 indicates that there is an issue with the use of the namespace in the group identifier within an OData service. This error typically arises when the namespace is incorrectly formatted or used in a way that does not conform to the expected standards.

  Modify Service Definition: If you have access to the service definition, modify the group identifier to remove any leading or trailing slashes.
  Regenerate the Service: If changes are made to the namespace or service definition, regenerate the OData service to ensure that the changes take effect.
  Check for Consistency: Ensure that all related configurations (like service bindings, annotations, etc.) are consistent with the corrected namespace.
