pulldata updates all relate recs

BKS

Hello

I have a feature service consisting of a FC and a related Table; relationships is FC 1:M Table.

When updating the values in the table all works as expected except... one field used to store the AGOL username ends up calculating this value for all of the records in the table that are related to FC.  When I update other fields it only updates the target record in the table. 

The difference is that I use the following in the calculation column:

pulldata("@property",'username')

I don't understand why it updates all related records?  

Is there a way to prevent this?

Thanks tonnes,

BKS

... How are you updating the values?

Editor tracking fields are system (Created by, Created date, edited by, edited date), it'll update with your editor username.

I'd you're using the Survey123 Inbox to edit existing records you might need to adjust the form behaviour:

• Prevent editing of existing related records (use the repeat parameters to prevent access or updates)
• Use formulas like Once() or WhenEmpty() to populate the related record with the username only the first time
