Sorry, we cannot move further until you will tell me if this SQL returns right data:
SELECT vendorID, ;
cnt(*) AS NumReceipts, ;
SUM(qtyrecv) AS QtyRecv, ;
SUM(qtyrej) AS QtyRej ;
FROM PoEntry ;
INTO CURSOR VndrPerf ;
group by 1
It doesn't mean that anything else Ok, but you claim that data result is wrong so you got to make sure firstly that this SQL really works for you.
