Hello all We are facing issues while closing the periods in AP

Hello all,

We are facing issues while closing the periods in AP, We havent closed the periods from start, we have checked the payable exceptional report, we have got some invoices with event type as Invoice validated and status as Unprocessed where as when i checked the same invoices in invoice work bench i didnt get any of the invoice, Only one invoice which was in Incomplete Status it was Appearing in Invoice work bench which i had cancelled.

please suggest where do we get the transaction with Unprocessed status which are validated and how to go further to close the periods
