What I would like to do is create a date sorted list of customer orders and purchase orders for a single item(part) and populate a single matrix.
and did i mention quick...
i suppose you sould create for example UNION query:
SELECT docdate, cardname, 'purch', docnum FROM OPCH
SELECT docdate, cardname, 'order', docnum FROM OPOR
ORDER BY 1
Then execute oRS.DoQuery and populate your matrix inside a loop...
propably, somebody can give you some more advices..
hope it helps..
