Yes, on the Customer Order "Print Invoice and Inventory Pick List" screen there is a field where you would indicate this order is to be a ‘Drop Shipped' order. When this field is changed to ‘Y' the items on this order are not removed from your inventory records. In the "Miscellaneous Definitions" area you can setup this field to generate a vendor purchase order so you can place an order with your vendor for the items on this invoice.
