Greg- How do I match a row from tblDownGrades with Sander? On ID? On Date/Shift/Thick/Width/Length/CSPCS, etc? If the match is on ID, which set of the nine common fields takes precedence? If the match is on the 9 fields, do you care which ID is used? Or generate a new ID? And finally, which table has more rows, and what do you want to do with rows that don't match in either table?
