The SAP error message /IWFND/CM_MGW_RT132 indicates that there is an issue with an association in your OData service. Specifically, it states that an association set is referencing a disabled association.

Cause: Disabled Association: The association that is being referenced in the association set is marked as disabled in the service definition. This can happen if the association was intentionally disabled or if there was a change in the data model that was not properly reflected in the service.
