Report Languages
You can specify the report language in the report properties or in your preferences. When you run a report, the language specified in the report properties is used. When it is not specified in the report properties, the language in your preferences is used.
Selecting a language for your report does not change the language used in the portal. You can change the language used in the portal interface in your preferences.
When a report runs, the report server connects to the underlying data source to obtain data. When using an SAP BW data source, if the SAP BW server does not support the language associated with your content locale, IBM® Cognos® Analytics checks a locale map for a corresponding locale. If the SAP BW server supports the language for the corresponding locale, this language is used. Otherwise, the report runs using the default language installed on the SAP BW server.
To specify the report language, you must have read and write permissions for the report and traverse permissions for the folder that contains the report.
The package used to create the report must contain multilingual data before the report outputs are shown in the selected languages.
