Multi Lang. Analysis for Excel over HANA Live

Experts,

I'm building a solution in which HANA Live content is consumed by Analysis for Excel reports (based on BO relational connection and not Excel ODBC/JDBC capabilities).

I've already created similar reports with Webi in which its connection is based on Universe and therefore multi language behavior is managed by BO personal user preference.

As for now, I was not able to understand how multi language (i.e., different users can see texts in different languages) is handled.

Please advice,

BR,
