AP Accural Reconciliation Report A/P No PO, Source for report amount

Can someone provide a means (qry or report) that will show the detail (source of data) for the A/P No PO amount showing on the Accrual Reconciliation Summary Report?

The value in the column AP-PO is visible by using the report named Accounts Payable and PO. (detail matches summary). We would like/need to be able to reconcile similarly for the A/P No PO data element.
