Hi Amir,
I keep getting an error when I try to apply the record name rule you showed in your demo:
00217: Invalid Acrade expression, Arcade error: Unexpected null, Script line: 2
I've checked my Records and none have null Names. I am wondering if the FeatureSetByRelationshipName function does not work in a file geodatabase? If that is the case, can you suggest a possible alternative way to use an attribute rule to populate the record name if my fabric is in a file geodatabase?
var RecordName = First(FeatureSetByRelationshipName($feature, 'RecordHasLand', ['Name'], false));
Return RecordName.Name;
Thanks,
Mike Z
