An account-specific catalog is not a separate catalog, but is simply a custom view into your store’s master catalog. Logged-in contacts who shop on your store can see and purchase only the products in the catalog associated with their account.
There are a number of tasks that you can perform only in the master catalog, not in an account-specific catalog. You can perform the following tasks only in the master catalog:
View details for a product or a collection.
Create a new product or collection.
Edit or delete an existing product or collection.
Rearrange products in a collection or rearrange collection hierarchy.
Access the following options from the Manage Catalogs menu: Product Types, Price Groups, Inventory, and Upload Media.
Any changes you make in the master catalog are automatically applied to account-specific catalogs, if appropriate. For example, if you add a new product to a collection that is part of an account-specific catalog, the new product automatically appears in the account-specific catalog. Remember that you must publish your changes before you can associate a catalog with an account.
