New

This status is assigned when a purchase order is created for the first time, before it has been released to the vendor. A New purchase order can exist without line items. If you make changes to a New purchase order, its status will remain New. Inventory quantities are not adjusted when the new purchase order is entered; they are adjusted when the purchase order line's status becomes Released.

Released

This status indicates that the purchase order has been sent to the vendor. A New purchase order is assigned a status of Released when at least one purchase order line changes from New to Released, or when a receipt is posted. A Change Order purchase order also changes to Released when printing it results in at least one Released purchase order line and no remaining Change Order purchase order lines.

Change Order

This status notifies people that the original order is no longer valid. When a purchase order with a Released status is edited in a way that affects the vendor, it is assigned a status of Change Order, and the revision number increases. Use the revision number to be sure you and the vendor are referring to the same order. The revision number will not increase when you make changes to a purchase order that already has a status of Change Order.

Received

This status is assigned when there are no quantities remaining to receive, but there are quantities remaining to invoice. A Received purchase order can have a combination of Received, Canceled, and Closed line items.

Closed

This status is assigned when all line items have been closed-there are no remaining quantities to receive or match to invoices. A Closed purchase order can also have Canceled lines.

Canceled

This status indicates that the purchase order will not be processed any further. A purchase order is assigned this status when all line items have been canceled and haven't been received against.
