    | Create a category | Create a relationship. | A relationship is a named part of a customizable product. Relationships contain one or more items. | 
    | Add a product to a catalog | Add a product to a relationship. | None. | 
    | Set item sequence in a catalog | Set sequence of items in Structure view and sequence of group in Product UI Designer. | None. | 
    | Hide items in the catalog | Can hide an item by not adding it to a UI group in the Product UI Designer. | All products included in a customizable product, plus all attributes, resources, and links can be made visible to users.  | 
    | Show all excluded items | Select UI control in Product UI designer that displays all items. | Excluded items are unavailable. | 
    | Create virtual product | Replaced with hidden attributes. | Virtual product functionality can be created by defining product attributes and then marking them hidden. Hidden attributes do not appear in quotes, orders, or agreements. |
