Situation:
Customers get annual invoices, there is no quotation or order left
Invoice was written in 2017
Some Prices have been changed in the meantime.
New invoice can be written now.
To save time, we want to duplicate the old invoice. But the new invoice gets the old prices again.
Is there any possibility to create a new invoice with the duplicate function with new prices?
you can override copy() function
Thanks
Can you tell me where to find it? I also had this idea, but I have searched for hours, and didn't find it yet.
