Wanting an advice on best way for bulk reversal of accounting of AP invoices.

Summary: We have a requirement to reverse the accounting of about 7000 invoices in our Production system. We were looking for a way to do this in bulk. We missed to add the below Journal line rule in our SLA config, due to which all the PO invoices have not generated PO Encumbrances.

Requesting help or suggestions on better ways to to correct the accounting for these transactions. Thanks in advance for any help that can be given :)
