No final invoice exists, revaluation is not possible

What causes this issue?

You have attempted to generate a settlement document for a purchase
order item for which a provisional invoice or one or more differential
invoices have been entered. However, no final invoice has been posted.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The system also considers held and parked invoices.

System Response

The system does not perform the revaluation.

How to fix this error?

If you want to perform the revaluation anyway, close the process by
posting a final invoice and then perform a revaluation.
