This is a custom dimension of the type "Product Category". Here static information on a product is collected.
"Added to Shopping Cart" means that only products with the product status "add" are considered.
Each metric combined with this dimension relates to products that were added to the shopping cart.
Hint: "-" classifies all products that are not assigned to a product category.
Unfortunately, we cannot provide further information on this analysis in the Support Center, as each product category is configured in your Webtrekk system.
