Hi, is it possible to make Rushmore optimization work here:?

Table1's PK expression is PKF1 + PKF2

Select PKF1, PKF2, Count(1) as nDup from Table1 group by PKF1, PKF2 ;
Having nDup > 1

Do I have to add any WHERE clause or any tip to see Optimization:Full?


Current result is "Optimization: None"

Thanks.
