I don’t believe the REQUIRED? setting has any meaning for virtual columns: meaning, even if ON, it wouldn’t be enforced.

Try using a Valid_If expression: COUNT([virtual-column]) > 0

unfortunately, it did not work

Have you confirmed your REF is returning rows, and the key column on the refereed table makes sense. As @Steve mentioned, you don’t set a REF as required because it’s just connecting to to source data you are referring to. That column and data in that table you can set to require…

I would check the source data first.
