When there is not enough stock on hand to fulfil an order, your final option for sourcing stock is always a purchase order. This might be manual or automatic depending on your company's procedures. The following diagram shows the process where the Auto PO Request procurement option has been setup with a default customer delivery option of Direct - that is, the supplier delivers the goods directly to the customer.
When the sales order is processed, the operator verifies the supplier for the item, receives the payment from the customer and prints an invoice. When the Automatic Purchase Orders program is next run, Micronet sends the purchase order to the supplier, which picks the stock and delivers it direct to the customer.
