Reduce invoice number by two digits

[azurtem]

HI

I'm trying to reduce the size of the invoice number by two digits to accommodate our invoice prefix

The number field in the order_invoice table only stores the number itself and not the leading zeros

Is it simply a case of modifying the format of the invoice number in the PDF template ?

I found this line in the HTMLTemplateInvoice.php :

$this->title = $order_invoice->getInvoiceNumberFormatted($id_lang,(int)$this->order->id_shop);

Any clues ?

thanks
