Michael, do you realize how long this takes to run when you are dealing with 
a lot of records (9391 to be exact)?

No burden... that was written on all smiles.  Hard to tell with text.
anyway... you will also need to change the where statement I gave you.  You
need to select the same record for both x and y.

WHERE x.QDDGRP = :WKGRP AND x.QDSDT >= :WKRUNDATE
    AND x.QDINST = :FIINST
    AND y.QDDGRP = :WKGRP AND y.QDSDT >= :WKRUNDATE
    AND y.QDINST = :FIINST

Ciao!
