SELECT  onfile.DealReference  
                    dbo.DCA_Detail AS onfile 
                    WHERE   onfile.DealReference NOT IN (  
                            SELECT  DealReference  
                            FROM    #tmpAllocatedDealReferences ) 

When I chose to "Qualify Object Names", it changed the subselect as follows.
NOT IN (  
                            SELECT  onfile.DealReference  
                            FROM    #tmpAllocatedDealReferences ) 

This introduced a nasty little bug, quite tricky to spot.

The DealReference field in the subselect should refer to the temp table.

I'd advise to all that you shouldn't consider the "Qualify Object Names" as purely cosmetic i.e. that if you're going to use it, make sure that you do so BEFORE testing.
