  The SAP error message /IWFND/CM_MGW_RT133 indicates that there is an issue with an association in your OData service. Specifically, it states that an association set references an entity set that has been disabled. This typically occurs in the context of SAP Gateway services where associations between entity sets are defined.
  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.
  Service Configuration: The OData service might not be properly configured to expose the entity set that is being referenced.
  Model Changes: Changes in the data model (like removing or disabling an entity set) without updating the associations can lead to this error.
  
  Solution:
  
  
  Check Service Definition:

  Update Associations:

  Ensure that all associations are valid and point to active entity sets.
  
  
  
  Regenerate the Service:
  
  After making changes, regenerate the service by right-clicking on the service and selecting "Generate Runtime Objects".
  Activate the service in the SAP Gateway (transaction code /IWFND/MAINT_SERVICE).
