Product Scope

For installations with multiple websites, stores, and views, the scope setting determines where products are available for sale, and the product information that is available for each store view. Initially, all products that you create are published to the default website, store, and store view.


Multisite Installation

If you have only a single store with the default view, you can run your store in Single Store Mode to hide the scope settings. However, if your store has multiple views, a scope indicator appears below the name of each field.

  • To edit product information for a specific view, use the Store View control in the upper-left corner to choose the view. Additional controls become available for any field that can be edited at the store view level.
  • To define the scope of a product in a multisite installation, see the Product in Websites section of product information.

The process of editing a product for a store view is like adding a layer of product information that is specific to the view.

Although the Spanish store view is selected in the following example, the product information still appears in the original language of the default store view. To translate the product information, you must switch to the Spanish view, and translate the text fields — such as product title, description, and the meta data. To learn more, see: Translating Products.

To edit a product for a different view:

1. In the upper-left corner, set Store View to the specific view to be edited. When prompted to confirm, tap  OK  to switch scope.

2. A checkbox appears below any field that can be edited for the store view. To override the default value, clear the Use Default Value checkbox. Then, update the field with the new value for the store view.
