There are three reasons this could happen:
- You have already sent an invoice. The Originator will need to decline the invoice before you can make amendments.
- You have created an invoice draft. Delete the draft and you will be able to amend the work order.
- You or the Originator have made amendments that have not been accepted yet. If the status of the work order is "Amended by Receiver" or "Amended by Originator," the other party will need to accept or reject the proposed amendments before either can make more amendments.
