Issue -- Payment made for invoice with wrong company code

Issue: We need help understanding what we should do with 2 unaccounted transactions, we will sweep them into August for now, but need to know how to clear them.

Essentially what happened is that invoice 10 was entered with 520 as the company segment into the France BU which was 600.  This created an accounting error that was not picked up until after a payment was made of it.  Now we have a payment that can’t be reversed/voided and an invoice that can’t be cancelled, so what should we do to clear these?

Solution:

Please unreconcile the payment from cash management, void the payment and then cancel the invoice and then create new invoice with correct company segment value 600.
