Problem with Purchase Orders in RMS SO 2.0 SP3

Greetings all, I've searched the forums and cannot find a solution for the problem that I'm having and I'd be greatful if anyone can assist. The problem is: All Purchase Orders are created in the back office, but whenever the personel tries to do a PO, whatever item the Cashier in the store scans, automatically adds itself to the PO in the back office. Example: Now, two seperate computers, on a LAN, both with hand held scanners, employee #1 creates a new PO, and starts adding items to the list, employee #2 selling at the cashier system in POS scans an item to sell to the customer. The item scanned shows up in the POS screen and the sale goes through as normal and customer leaves. But, the same item that the cashier has scanned ALSO shows up in the PO created on the other computer at the back office. And employee #1 (creating the PO) now has to delete this item before continuing the PO.

I have updated all systems to latest Service Packs and Hotfixes, and tested again and the same problem occurs.

Has anyone else had this problem? Can anyone suggest a possible solution? Is this a known problem?
