I am trying to create a very simple custom report, i based it on a GI that works just fine. The goal is to first put in a customer, then to select one of the customers locations. (all based on the SOOrder table)
However, in the report i cant get a simple Parameter dependency to function even after following several online threads on how to update the report from the GI.
I added the “,CustName” reference to the end of the GetFieldSchema, just as suggested in topics and as I saw it done on some stock reports, but the field never populates no matter what customer is selected.

I have this sneaky feeling that i’m missing something obvious/simple and I hope some fresh eyes will be able to point out what I missed.
Edit: The CustName parameter works fine, it filters the report as intended.
