[TYPO3-shop] [Typo3-shop] Additonal Fields/Marker for Orders

[Clemens Tilgner]

Hi,

i have created a shop with Products, which have a lot of different variants. 
In the Productconfiguration Process i generate with Javascript a Code, which 
the User can enter in a field, to recreate this specific product. The idea 
is, that you can send this code to other people, so that they can recreat 
the same product.
I would like to add this code into the order process, so that the customer 
finds the individual codes to each order in the checkout process and order 
confirmation.

How can i add such a marker, which is filled, when the basket is send and 
then appears in each order?
