Dear Florence,
In the Survey Designer, for every attribute, in the **Labels and Tooltip** section, you have the possibility to specify even **Other labels** (just click on the title of this box and it will be opened).
Among these extra labels there is a **Reporting (Saiku) label** that is used to generate the label of the corresponding *Dimension* or *Meaure* in Saiku. If not specified, the default label will be used.

I hope this will help you, thanks.
