Payble purge prerequisite for unpaid invoice

Hello Expert!

In the Payable User guide, it's montionned that Invoice Purge Criteria are:

Invoice is fully paid or is a zero-amount invoice

Invoice is transferred to general ledger

Invoice is not a prepayment, and no prepayments have been applied to the invoice

All of the invoice's payments meet the Payment Purge Criteria

No open encumbrances are associated with the invoice

All purchase orders referencing the invoice meet the Purchase Order Purge Criteria

If Oracle Assets is installed, all of the invoice's distributions were tested by Mass Additions

But when runing the purge program- it's seems taht the unpaid invoice was not purged, only cancelled invoice is taking from the purge program. did someone faced the same thing as us?
