items not taken out of inventory

Like jim I have had items received, sold , returned for credit and returned to the dc. My system still shows the product in stock. Exploris help desk thinks that it has something to do with items not sourced on the system. Ie; if I buy something from montreal and return it before receiving my e-invoice, the system does not go into a negative on hand , so that when it is received on asn , it would bring the on hands back to 0. They say they are aware of this, but who knows when they will fix it. Makes inventory control interesting!
