User langauge for broadcasting

Hi experts,

When I create a broadcast setting, I can choose only French or English for the language. But we want to send the report to german users too.

In the SAP help I found this : The system offers you a choice of the languages that are installed in the BI system.

Does that mean that the german language is not installed ? However, we can log in SAP BI in german.

Any idea ?

Thanks in advance
