Purchase order statuses

Every PO has a status that tells you where it is in its lifecycle. POs that use an approval workflow also carry a separate approval-request status alongside the PO status — they are two parallel concepts, not the same field.

The six PO statuses

draft — created but not yet sent to the supplier. Fully editable.
sent — emailed to the supplier and awaiting fulfillment.
partial — some line items have been received but the PO is not fully fulfilled.
received — all line items have been received in full.
closed — you have manually closed the PO; no more stock will arrive.
cancelled — you have cancelled the PO; it will not be fulfilled.

Approval-request status (separate concept)

If approval workflows are enabled on your plan and the PO falls under a workflow, an approval request is attached to the PO. The approval request has its own status:

pending — awaiting approver decisions.
approved — all required approvers approved; the PO can now be sent.
rejected — one or more approvers rejected the PO.

The approval-request status shows in a banner at the top of the PO. The PO status itself stays as draft until you send it after approval — the approval status does not replace the PO status.
