  The SAP error message /IWBEP/CM_MGW_RT133 indicates that there is an issue with an association in your OData service. Specifically, it states that the association set references an entity set that has been disabled. This can occur in the context of SAP Gateway and OData services when there are issues with the configuration of the service or the underlying data model.
  Cause:
  
  Disabled Entity Set: The entity set referenced in the association is disabled in the service definition. This can happen if the entity set is not included in the service or if it has been explicitly marked as disabled.
  Model Configuration Issues: There may be issues in the data model configuration, such as incorrect associations or references.
  Service Registration: The OData service may not be properly registered or activated in the SAP Gateway.
  Authorization Issues: There may be authorization issues preventing access to the entity set.
  
  Solution:
  
  
  Check Entity Set Status:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Open your project and check the entity sets defined in your model.

  Regenerate the Service:
  
  After making changes, regenerate the service by right-clicking on the project and selecting "Generate".

  Check Service Registration:
  
  Use transaction code /IWFND/MAINT_SERVICE to check if the service is properly registered and activated.
  If the service is not active, activate it.
  
  
  
  Test the Service:
  
  Use the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to test the OData service and ensure that the association works as expected.
