Neither the Dynamics AX nor OData connector can retrieve a custom entity that is defined as an enumerator data type. The preview operation within ADF retrieves other standard fields that are defined as enumerator (it translates those fields automatically) except custom defined entities. Power BI's OData connector oddly enough works. It has no trouble bringing in a custom entity and doing the translation. This tells me that the Power BI team has figured out how to do this but the ADF team has not.
Is there a workaround for this that does not require a redesign of the custom entity?
