May generate invoice number before sending mail


Just a slight worry found:
With in the parameters of the invoices
"Generate Invoice Number Invoice Drafts" is set to “No”
“Mark invoices as sent when PDF is generated” is set to “Yes”

The invoice creation is OK.
When I send the invoice by mail "without the invoice number generated"
This sends an invoice in PDF and the mail without invoice number …
But this generates and saves the invoice number in the system after sending it.

So what I have to do before sending an invoice by e-mail is to put the invoice status in Sent, save the invoice and send it really.

It’s not blocking, but I think it may help if I point it out.

Sorry for the moving @Kovah
