Hi,all:

      If there's a product called "demo", and there are three warehouses for storage.

      In each location we have  500 "demo",1500 in total.So in product.tree I can see“Quantity On Hand” is 1500.

      But if  only location A and location B is for sale,once salesman come to Sale->product,the"1500"

date may mislead him--only 1000 "demo" can be sold.

     Is there anyway to let me calculate  the “Quantity On Hand” for the specified location？In this case

I wanna location C's quantity   invisible for salesman and let the product.tree display the “Quantity On Hand” as "1000"?

    Thanks!
