  The SAP error message /IWBEP/CM_V4_COS123 indicates that the service alias cache for a specific service group is outdated. This typically occurs in the context of SAP Gateway services, particularly when there are changes made to the service definitions or when the cache has not been refreshed after updates.
  Cause:
  
  Service Changes: If there have been changes to the service definitions, such as adding or modifying entities, the cache may not reflect these changes.
  System Updates: Updates to the SAP system or the underlying data model can lead to inconsistencies in the cache.
