This is a custom dimension of the type "Product category". Here static information on a product can be tracked.
"Purchased" means that only products with the product status "conf" are considered.
Each metric combined with this dimension relates to purchased products.
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 Mapp Intelligence system.
