product code in mail order

Hello is it possible to send product code via mail?
when customer makes an order and i get an email with his order there is no product code only name of the product he ordered.
is it possible to send it?

Hi,
Sure, the solution will be to set the "Display product code" option to YES through "Hikashop->System->Configuration->Display"

Yes I had it set to YES but when a mail with customer order is delivered to my mail box I see only product name. On the website it is displayed correctly also in hikashop backend.
