A Vendor Shipment Sales Order is audited when it is created or edited. The system will place the sales order on hold for various reasons if it is appropriate. If a Vendor Shipment sales order is on hold, the system will not allow the PO Requisitions for the Sales Orders to be processed (converted to purchase orders). The holds for the order must be released before the PO’s for the order can be placed. This prevents you from telling a vendor to ship something to a customer before credit or other staff is able to review and approve the order.
