Hi,
I have created a few invoices and realized that there is an error in how I number my invoices. I want to change the following
Invoices generated with the following syntax AT-INV-{mm}{yyyy}-{000@4} need to be changed to INV-{mm}{yyyy}-{000@4}
I have made the necessary changes in the invoice module and I assume future invoices will have the correct numbering but how do I update the same for the invoices that I have already generated and validated.
