Hi,
I am wondering why it's possible to add a relationshipClass from the catalog into a map in ArcMap 10.3 only when the cardinality is M-N (many-to-many). When I try to drag and drop other relationshipClass with cardinality (1-1 or 1-M) I have the following error:
Could not add the specified data object to the map.
Thanks for the info,
Maxime
