Cognos® BI and locale
You can install a localized version of the Unica application report package (other than English) by setting the product language to match the language of the application report package.
On the system that runs the Cognos® Content Manager, open Cognos® Configuration, select Actions > Edit Global Configuration, and configure the locale for the Cognos® BI system. For more information, see the Cognos® Configuration User Guide, available from the Help menu in Configuration Manager.
You can change the product language for the specific user by setting the product language to match the language of the application report package. To set the product language, open Cognos Connection, and under User Preferences set the corresponding product language. You should not change the content language. If the content language is changed, then the corresponding xpath for the reports should also be changed.
