SQL, script or API for discarding, rematching and recalculating PO matched AP invoice lines

Hello,

As our supplier tax rate will change soon, we need to include the non-recoverable tax amount into our existing ap invoices

I would like to know if there are any SQL, script or API for discarding, rematching and recalculating PO matched AP invoice lines, because we might have big number to update.

Thank you.
