# Read an order's history Send and amend an approved order, then read every recorded change in its history. Source: https://help.smartfact.ai/purchasing/guides/purchasing-order-history Audience: Supervisor Sarah Hughes is signed in with only the Supervisor role and a recent security check. HP-PO-01001 is approved for two hours of machine calibration. She records how it was sent, amends it to one hour and approves the amendment. ## Read an order's history 1. **Open the approved orders** Open the approved orders. Sarah uses her Supervisor role to record a supplier communication. A recent security check is required. 2. **Check the approved calibration order** Check the approved calibration order. Open HP-PO-01001 and check the approved revision. It authorises two hours of machine calibration. Downloading or printing its document does not record a send. 3. **Record a communication already made** Record a communication already made. In this scenario Sarah has entered the approved order in Calder Fixings' supplier portal and retained its acknowledgement. Record that completed communication here; this button does not contact the supplier. 4. **Choose the supplier portal** Choose the supplier portal. Choose the method actually used to communicate the approved revision. 5. **Keep the destination and reference** Keep the destination and reference. Retain the supplier portal and acknowledgement reference so another person can check the communication. 6. **Record the communication time** Record the communication time. Enter the local equivalent of 14 October at 10:00 UTC for this lesson. Help displays and types the value in your browser time zone. In your work, record when the communication actually happened. 7. **Keep the communication evidence** Keep the communication evidence. Keep a short description of the acknowledgement with the send record. A communication record does not prove supplier acceptance of the order terms. 8. **Save the send record** Save the send record. Record the completed communication against revision 1. The approved quantity and order identity stay the same. 9. **Prepare a change to the sent order** Prepare a change to the sent order. The calibration visit now needs one hour instead of two. Open an amendment; the approved revision remains in force until the change is approved. 10. **Reduce the proposed quantity to one hour** Reduce the proposed quantity to one hour. Enter the revised quantity in hours. Keep the original line identity so the history remains connected. 11. **Propose the revised visit date** Propose the revised visit date. Request the visit on 22 October. Check the date with the requester before approving the change. 12. **Explain the revised requirement** Explain the revised requirement. Keep the instruction that the supplier needs with the proposed revision. 13. **Save the amendment draft** Save the amendment draft. Save revision 2 as a draft. Revision 1 remains in force, including its approved two-hour commitment. 14. **Submit the proposed revision** Submit the proposed revision. Submit the one-hour amendment for approval. Submission still leaves revision 1 in force. 15. **Approve the reviewed amendment** Approve the reviewed amendment. This site has a reviewed one-supervisor rule. Sarah can approve revision 2 after checking the quantity, date and note. Approval changes the commitment and creates new documents; it does not communicate the revision. 16. **Read the order history** Read the order history. The order history keeps every change in order, with its time: the original submission and approval, the recorded send, the amendment and its separate approval. Earlier revisions and their approvals stay on record. [Watch or practise this chapter](https://help.smartfact.ai/purchasing/demo?guide=purchasing-order-history&chapter=order-history&audience=office) The order history is a record, not a draft: nothing in it can be edited. Use it to answer who approved what and when, alongside the send history and the recorded rule checks.
