how to join featureclass data based on a predefined relationship class in arcpro

Question

How to join featureclass data based on a predefined relationship class? The option does not seem to exist in ArcPro as it did in ArcMap.

Hi Mike.  Looks like you asked this last year as well https://community.esri.com/thread/208980-is-there-featureclass-join-option-based-on-predefined-relationship-class-in-arcpro.  That option doesn't currently exist in ArcGIS Pro so it might be helpful to submit this on the ArcGIS Ideas site so that we can get a better sense for demand and use cases.  We've tracked and implemented a number of ArcMap equivalency issues through Ideas...

For now, you could just look at the relationship class' properties and use those to create the join in the Add Join tool:

Cheers
