Store catalog and category structure
Key Takeaway
Categories are the top-level classification of products in a store's catalog, so give each product line its own top-level category. When a product sits in several categories, the primary category sets the breadcrumb path on the Product Detail page.
A catalog is the entire collection of products you offer through a B2B Commerce store. Inside the catalog, you build a hierarchy of categories and subcategories. Categories group products so buyers can find them through search and navigation. How you set up this structure decides what buyers see in navigation menus, filters, and breadcrumb paths.
Catalogs and stores
A store must have a catalog before you can make products available to buyers. A store can have only one catalog at a time, but you can assign one catalog to more than one store.
When you create a store, the store gets a default catalog named after it. The default catalog includes one default category, named Products. You can keep the default catalog or assign a different catalog to the store.
The default Products category is the only default store record you can delete. The other records created with the store, such as the default catalog, can't be deleted.
An admin creates a store named Harbor Supply. The store gets a default catalog named Harbor Supply Catalog, which holds one category, Products. The admin can delete the Products category but can't delete Harbor Supply Catalog.
