I am trying to set up a Field Map which can auto-populate an inspection field in a related table from an existing point
I created the Relationship Class - we can call 'Rel_Name'
Then in Attribute Rules for the table I created a Calculation rule as follows:
"var parent = FeatureSetByRelationshipClass($feature, 'Rel_Name', ['Field_Name'])
return First(parent)"
Validating throws the following error - "Invalid expression. Error on Line 1. Unknown Function."
Can anyone advise?
FeatureSetByRelationshipClass was released in the most current version of Arcade (v1.24), which may not work in Field Maps yet. Can you use FeatureSetByRelationshipName instead?
