In a multisite environment, your administrator associated specific catalog assets (catalogs, catalog folders, categories, products, and SKUs) with specific registered sites. The Sites property on an asset’s General tab in the Details pane shows you which registered sites this catalog belongs to.

You cannot directly edit the Sites property for a Catalog asset, but you can associate assets with different registered sites by linking or moving them. See Linking and Unlinking Assets and Moving Assets. You can, however, directly edit the Sites property for a Promotion. See Creating and Managing Promotions and Coupons for more information.
