Defining Languages for OLAP Data Sources
The first time you publish a cube definition
to IBM® Cognos® Connection, you must identify all the
languages that represent the data contained in the cube. If you add
a language to the model after the cube is published, users with locales
that match the added language locale may find that Analysis Studio
does not recognize references to the member unique names. There is
no impact on users whose locale matches the original language list.
