Ensure that those receiving reports get those in their preferred language.
When you create reports based on templates you can determine what language they should have. To create a new language, go to Report Translations under the Reports section, then click "new" in the upper right corner.
Give your report translation a name and description of your choice. Next, set the locale to control such things as number and date formats.
The default language lets you choose English or German as the basis for the translations.
Next, click "edit default translation" for any fields you would like to translate, and then add your translation. Finally, click save.
