Whenever a customer changes their billing address on the website, it changes all their addresses on their previous invoices that used the billing address to the new one. This is a big problem as invoices need to remain unchanged when you store them. I have asked odoo, but they say it is how odoo is meant to work. It is a big issue so I am surprised it has not been fixed.
Is there any quick fixes to this?
How can I record the original delivery and billing addresses of the invoice so that a copy of the original data is preserved and not changed?
I want to do this without adding code or modules (using code inside odoo is fine though, e.g automated actions executing python code is fine)
Thanks for the Help!
