Hello everyone,
I am having the following problem.
I have a parent feature layer (globalID) and 4 child tables (parentGuid).
I wrote this simple arcade expression to access the related table attribute:
Try returning them as just as the variable, without the Text() method. This should allow us to see what data is present in the featureset.
I re-imported the csv table into ArcGIS Pro, did everything again, this time reducing the size of the fields via the schema.ini file. I don't know if this was the problem or not, but now the expression is valid.
I can move on.
Thanks a lot for the advice @AustinAverill and the support
Must have been some sort of issue like that! Very odd, but glad you were able to resolve it!
