We have approval pathways that, for certain specific suppliers, goes to one person then to a second approver. Generally all other suppliers go to the second authoriser straight away.

If there are invoices that have been first authorised, waiting on the second authoriser, and I add a new supplier into the approval pathway for the double approval process, any invoice that has been previously authorised by person number 1 and not number 2, goes back to the inbox and has to be sent for person number 1 to authorise again.

Would like to suggest that once an invoice is approved, that it doesn't get rejected by the system is a change to the approval process occurs.
