How to update a PO, which is in a closed status and fully costed

The business has raised a PO, but after receiving, invoicing and fully costing, it was realized that the PO is wrong, some lines need to be updated with new quantity and price and some needs to be deleted.

What should be the workaround in this case, as the costing entries are generated, and PO is in close status.

I am also attaching a PDF for the case summary.
