Hi Team,

 

I am having an issue trying to get an attributed many to many relationship to appear in portal, specifically in Experience builder.

 

Right now I have a Point layer of Ports, and a Table of Ships.

 

In Arcpro I have an attributed relationship class (Many to Many) set up that works just fine in Pro. But I am unable to find the relationship in the Forms widget in the Web Map, or in the Edit widget in Experience Builder. 

 

My question is there a specific way to set up M:N relationships that I am missing?

 

Regards

Map Viewer only supports 1:M and 1;1 relationships. M:M is not supported.
