It would be most beneficial to have the Purchasing Vendor Cost on the Short-Buy Screen instead of the "Wholesale Cost". The Contract/Wholesale Vendor Cost that is Asterisked on the Vendor Screen should be the Cost & record you see. It is the cost you're paying for that product. The Wholesale cost means nothing if you have other pricing.
John, while that is a good idea, and we use it for some scenarios, we may have reasons for still wanting the standard wholesaler cost showing in the wholesaler file as it can also impact pricing for some accounts. Therefore, I would vote for the initial request of having DDMS add the Purchasing Vendor cost to the ASB grid, even though you mention the workaround.
Here is how I get around that -
Go to +E-A, (or Keyop Menu, Specials, E-A). If you select 5 (Update Wholesale Cost), and base it on A (Purchasing Cost), then it should resolve your problem.
