Can a PO be finally closed if an open invoice is matched to it?

Hello,

We have a situation where a PO with an open invoice was finally closed.  Is this ability considered to be standard Oracle functionality?

The $210.60 PO was created on 11-MAR-2015 and closed on 13-MAR-2015.  The PO was finally closed the other day, on 15-MAY-2017.

There were two invoices matched to this PO; one was matched in error.  The first invoice in the amount of $200 was received on 13-MAR-2015; the second invoice in the amount of $190 was received on 11-MAY-2017.

Should we have been able to finally close the PO on 15-MAY-2017 if the open invoice was created only a few days earlier?
