AP invoice validation...

Hi, 

After a payment is processd, check issued, cleared and reconciled/accounted. Can we unreconcile, unclear and void the payment and re-issue a check? I know we can unclear if the payment status is cleared. But if it is cleared and reconcilied/accounted, can we undo the process?

 

Scenario: In the month of Apr 2011, a payment/check was processed for a vendor , however vendor deposited the check in his bank account 6 months later. But the issuing bank cleared the check when submitted and sent the bank statement as cleared. Later bank realized the check is pass due and declined the payment, returned the check to vendor. And now vendor wanted a new check.  Any thoughts?
