Posting Purchase Orders
When you post a purchase order, item quantities on purchase order are increased in Inventory Control.
If the purchase order is job-related, Purchase Orders also update the committed quantities and costs for the job in Project and Job Costing.
If you use the automatic-numbering option, posting assigns and displays the purchase order number. Posting also updates the information for the Purchase Order List, so that you can print an accurate list immediately. After posting, you can also print copies of the purchase order.
Posting completes purchase order lines that you set to Completed. You cannot edit these lines after posting.
Effect on requisitions. If you specified requisition numbers for the purchase order, the requisition detail lines you add to the purchase order are completed on the requisitions when you post the purchase order.
If a purchase order completes all the details on any specified requisition, the requisition itself is completed when the purchase order is posted.
