In Magento, Configuration scope refers to ability of a configuration parameter, product, category, attribute definition, or customer management setting to apply to a specific view.
You can switch configuration scope at the left top corner in Magento Backend:
- Default config (Global): This option refers to the entire Magento installation.
- Website level: Websites are ‘parents’ of stores. A website consists of one or more stores. Websites can be set up to share customer data, or not to share any data
- Store: Stores are ‘children’ of websites. Products and Categories are managed on the store level. A root category is configured for each store, allowing multiple stores under the same website to have totally different catalog structures.
- Store View: A store needs one or more store views to be browse-able in the front-end. The catalog structure per store view will always be the same, it simply allows for multiple presentations of the data in the front. 90% of implementations will likely use store views to allow customers to switch between 2 or more languages.
Please note, that some options can be set only for certain scopes. In example, Timezone can be set only on website level and used for all stores and store views of this website.
