I have a relationship class defined for my land-use zoning layer that is linked to a table containing zoning descriptions. I want to define a popup that shows the zoning code and the zoning description from the related table. I have defined a map service using ArcMap which contains the zoning layer which contains the relationship class. When I view this service in Portal Map, I do not see the related fields when I go to define the popup. However, if I define the relationship in ArcMap, it will show up in the Portal Map popup configuration but it now contains duplicate tables (presumably one for the relationship class and the other for the relationship defined in ArcMap). Is there a way to only access the relationship class fields?
Thanks! Steve.
