How can I correct an invoice without issuing a credit note?

I am importing old invoices (so already posted) because our company will start using Microsoft Dynamics 365 Business Central very soon.

But first I need to import all the invoices we have and by mistake we imported an invoice with an error, and now I need to correct it without emitting a credit note, because these are not new invoices, but it's about only a type mistake.

The invoices have already been posted some months ago, because we are starting only now to use Dynamics and now we are importing all the old data.

I cannot issue credit notes and issue a new invoice for my client because it is an old one and we already sent this invoice to the client and they already paid.

I only need to correct a small typing mistake made while importing data.


Waiting for you help. Thank you.
