Most views in the Apps offer a market selector, determining which market the merchandising action will impact. For some views, a locale option is additionally provided when multiple locales are available for a market. The locale does not limit the effect of the merchandising action to the selected locale, but controls the locale of the merchandising experience.
For example, when creating a promotion on a market, this promotion will impact all requests on that market regardless of locale. However, when searching for products to promote in the App, the locale in which to search is determined by the selected locale. Merchandising locales are available for promotions, demotions, and category and landing pages.
This means that merchandising actions only needs to be set up once per market and will automatically apply for all locales, regardless of selected merchandising locale.
There is one exception to how locale is applied, namely the navigation view. The navigation primarily consists of localized data, only relevant to visitors using a matching locale. For this reason, the navigation is separate for different locales on multilingual markets.
