Can anybody help me please, i can not find the the input field for the EAN Product Code. There must be one, because when i make a export there is a field for the EAN Code. Thanks for Help.
There is no "EAN Product code" by default in HikaShop.
There is a product code field (and you can store the EAN product code if you want) and there are "product custom fields" which allow you to extend the fields for products.
