Use a Localized Template
You can create localized templates for reports.
If you need to design a different layout for the reports that you present for different localizations, then you can create new RTF file designed and translated for the locale and upload this file to the Template Manager.
The localized template option is not supported for XPT templates.
Design the Localized Template File
Use the same tools that you used to create the base template file, translating the strings and customizing the layout as desired for the locale.
