Oracle BPM Worklist can be configured to set the language from the browser or from the identity store (LDAP). There are two levels to this setting: the application level and the user level. If the user preference is set, as LDAP in the user setting, it takes precedence in determining the worklist display language. If you do not set a language in LDAP, worklist follows default language as server locale. However, email notifications always follow the language set in LDAP. If no language is set in LDAP, email notifications follow server locale.
