You can place a Purchase order 'On hold' only at the header level. This approves the purchase order while preventing PRINTING, receiving, INVOICING, and future APPROVAL until you remove the hold. You can 'Freeze' only at the header and release level. You freeze a Purchase order when you want to prevent any future modifications to the Purchase order. When you freeze a Purchase order, you can still receive and pay for goods you already ordered. If you use a Requisition template or AutoSource to source requisition lines from a Purchase order line, Purchasing does not automatically update the corresponding sourcing INFORMATION when you freeze a purchase order with which you source requisition lines. If you freeze a purchase order, you have to update the corresponding information in the Requisition Templates or the AutoSource Rules window.
