Attributes are the characteristics of a product.
An attribute can be a specification of size, packaging or quality, but also information about storage bin, customs status or EU tariff code.
Food varies , and a product can have different characteristics from lot to lot, even though, they are the same SKU, e.g. apples and wheat can vary in size and quality.
When handling food, it can be very practical to be able to assign attributes that are as variable as the product.
In tracezilla you can assign different attributes to multiple lots of the same product.
