Metadata objects can be translated into different languages by exporting them to external database and re-importing them back. This export of translation tags can be performed using the Repository Translation Wizard (MicroStrategy Object Manager).
To export the language translation to a database, make sure there is a ODBC (64) connection of the database on the PC/server.
Once all the translations have been complied and they should be imported back into Microstrategy metadata. This process is similar to above, instead of selecting export, select import Translations.
