Concur now offers the ability for users to change a transmitted purchase order and resend it through the same workflow. Users are able to add line items to a transmitted request and enable the request go through the workflow again--including approval and processing. The system creates a new version of the purchase order, but with the same PO number.
Using the Invoice Settings tool, administrators need to activate this feature by selecting the Enable Change Order check box. The default setting is cleared (disabled).
