Translation Management Using Translation Collections
If you have the Multi-Language feature enabled, you can edit translations with a translation collection. Manage your translation collections using the Manage Translation feature. For more information, see Manage Translations.
A Translation Collection is a customization object that stores translation strings with their translations. One Translation Collection can contain many translation strings.
If available, you can edit a translation on the Translation subtab, but editing in the UI has limitations. You can, for example, override a field label on the Translation subtab of a custom form definition. When you translate a field label on the Translation subtab of a custom field, the translated label overrides the language set up in Home > Set Preferences. Language changes are visible only to users with the same language preference. For example, if you change the language from English (US) to English (International), only users with the English (International) language preference see the changes. For more information about translations, see Configuring Multiple Languages.
If you use SDF, make translation changes in SDF XML with a translation collection. If you enter translation strings directly on a form, they're not connected to terms or translation collections. The translations are visible only to users with the same language preference. If you change your language preference, you'll need to add translations for that language too.
