I have a union query which lists salesperson, GP and date of sale. There are 2 salespeolpe fields so this query unions salesperson1, GP and date of sale with salesperson2, GP and date of sale. The problem I have that there is occasionally duplicate information (for example a salesperson would have the exact GP and exact date listed twice (just because he happened to have the same GP for 2 particular sales on the same date)). My union query does not recognise this and one of the record just dissapears. Is there any way I can prevent this? I thought that perhaps if I sum the GP field then it will be added together instead of unioned but I don't think this is possible in a union query?
