5.2. Purchase Order

A Purchase Order is a written authorization used to formalize purchase transactions with Vendors. Purchase Orders and/or Purchase Order Line Items can have the following statuses:

Unposted ("U"): This is the initial state a Purchase Order receives when it is first created. As long as a Purchase Order is unposted, it may continue to have additional Line Items added to it. The List Unposted Purchase Orders screen will display all unposted Purchase Orders.
Open ("O"): The status of a Purchase Order after it has been posted. Line Items may no longer be added to a posted Purchase Order.
Received: The status of an open Purchase Order Line Item when the full quantity has been received.
Partial: The status of an open Purchase Order Line Item when only part of the full quantity has been received.
Closed ("C"): The final state of a Purchase Order after it has been closed.

Tip

A Purchase Order will remain open if at least one of its Line Items is open. Once all Line Items are closed, the Purchase Order will also be closed. To reopen a closed Purchase Order, simply open one of its closed Line Items.
