I am new to both Arcade and Attribute Rules. I am trying to create a calculation rule that is triggered by inserts, but my expression using FeatureSetByRelationshipName doesn't seem to be doing anything.
Here is the expression:
var test = FeatureSetByRelationshipName($feature, 'FH_MR_TR_REL', ["COMMENT_"], false);
return test;
I am applying the attribute rule to a table and trying to pull data from a field in a related feature class. 'FH_MR_TR_REL' is the relationship class and 'COMMENT_' is the field in the related feature class that I am trying to pull from.
I didn't get any errors, but the destination field remains null after inserting a new table record. I am sure I missing something obvious; any help would be appreciated.
