About languages and translations in App Builder
You can customize App Builder projects to use languages other than the default language,
U.S. English. App Builder uses two sets of options to accomplish this kind of customization:
Languages and Translations, which are both project-level settings.
Unlike some other Infor products, such as Mongoose, App Builder comes with no built-in language packs. To use other languages for your App Builder projects, you must both specify a language for the project and provide translations for any components or component elements that you want to translate. You can also provide translations for global strings used throughout the application.
