Information On Issued Invoices Should Never Change!

[Max]

Right now if one changes anything on the client profile -e.g. the customer's name or address- and generates a pdf of a previously issued invoice, it will contain the new information, instead of the data as it was on the day the invoice was issued.

This violates the VAT accounting rules that most European countries have, that do not allow changing anything on an invoice once it has been issued. 

 

Having an "edit" button next to the invoice poses a problem as well.

The only legal way to correct an invoice here is to issue a "credit note" -which is an invoice, with a negative amount on it- and then create a new one.

This is something we've been thinking about for a while. Added CORE-923 to handle invoice caching. Will likely be in 3.2 or 3.3.
