There should be a dynamic variable with the name
of a temp table in it [$Temp_Final_IDList] after the last INNER JOIN shown.
The select statement (submitted in my original question) shows the variable.

It’s like everything after the INNER JOIN is ignored. I did run tests to display
the contents of the variable to make sure it wasn’t empty and it wasn’t!
I’m kind of clueless what to try next!
