• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT003 - Metadata cache on hub system for current model is outdated ?

  The SAP error message /IWBEP/CM_MGW_RT003 indicates that the metadata cache on the hub system for the current model is outdated. This typically occurs in the context of SAP Gateway and OData services, where the metadata cache is used to improve performance by storing the metadata of OData services.
  Cause:
  
  Changes in the OData Model: If there have been changes to the OData model (like changes in the service definition, entity types, or properties), the metadata cache may not reflect these changes.
  Service Activation: If a service has been activated or reactivated, the cache may not have been updated accordingly.
  System Configuration: There may be issues with the configuration of the SAP Gateway or the backend system that prevent the cache from being updated.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Refresh the Metadata Cache:
  
  You can refresh the metadata cache by using the transaction code /IWFND/MAINT_SERVICE in the SAP GUI.

  Clear the Cache:
  
  You can also clear the cache using the transaction code /IWFND/CACHE to clear the cache for the OData services.
  After clearing the cache, you may need to restart the SAP Gateway service.
  
  
  
  Check Service Activation:
  
  Ensure that the OData service is properly activated in the SAP Gateway. You can check this in the same transaction /IWFND/MAINT_SERVICE.
  
  
  
  Check for Errors in the Backend:
  
  If the issue persists, check the backend system for any errors or inconsistencies that might be affecting the OData service.
  
  
  
  Re-deploy the Service:
  
  If necessary, you can re-deploy the OData service to ensure that all changes are correctly reflected.
  
  
  
  System Restart:
