AMEND ADDRESS ON EXISTING SALES INVOICE

Hi,

Hope someone can help me. I sent a sales invoice through the sales orders function. It was a new client and I had the wrong address.

The customer is requesting the invoice with the correct address but I can't seem to be able to amend it. I did change the address on the customer account (211) but when I ask to reprint invoice it still shows the old, incorrect address.

Is it possible to edit this invoice?

Many thanks
