Language locales can be created to contain language translations of the names for system transaction types. A default locale of System_US_English_locale already exists, which has the standard locale of en_US.
Locales are also used for translations of product catalog elements. For elements that are defined in open text fields, a translation link is provided next to the field. The translation link opens a menu to select a locale and define a translation for the field. See Multi-language Translation of Product Elements for more information.
Any user-created locales can be edited from the Locale Settings page. If the locale is already used by an email template, then a lock icon displays and locked locales cannot be deleted. Likewise, if it is a system locale, then a system icon displays and system locales cannot be deleted or edited.
