Field templates specify what information can be stored in each object. The field templates for products are divided into the levels base product and variant.
The field templates for the Products area can be found in back office, Settings > Products > Field templates.
System fields
There are a number of predefined system fields.
The system fields are always available, but if they are to be shown in the back office administration, they need to be added to field templates.
Below are the most important system fields when modeling products.
Article number
The article number always exists on both the base product and variant level, and it is not part of any field template. Article number is mandatory both on the base product and variant level. Once the value is set, the user cannot edit it.
Name
Can be set to both levels, or either one of them can be used.
Description
Both levels or either one of them can be used.
Images
Always exists on both levels, and is not part of the field templates.
URL
The URL is set either on the base product or the variant level. It is the display template specified in the field template that defines whether the URL of the base product or the variant is to be used.
The URL is set on the variant level if the variant itself should be browsable, that is it has its own URL.
In the case when all variants are shown as a list on one page, it is better to place the URL on the base product level.
The URL settings from the display template are also used when the product is indexed. If the URL setting is Variant, all the variants will be added to the search index as individual items. If the URL setting is Product the search index will only add the base product with all the variants as one item.
Variant grouping
The field specified is the field that will be used to group the variants for a product.
An example is clothes that have Size and Color as fields, where you typically want to group using the field Color. Users visiting your site would in product listings and search results see the products in different colors presented, and not all sizes repeated.
