PO Receipt Reversal

When a user reverses a PO receipt the transaction is flagged as reversed and the QTY is reversed out of inventory, but there is not any documentation of when the receipt was reversed. The transaction that is created when the receipt is reversed is a duplication of the original receipt with a negative qty. This makes it impossible to reconcile purchase receipts month over month because if something is reversed in a later period it shows the reversal on the original date.
