SSRS with Tabular cube - using hidden columns in query

Hi Everybody,

I created a tabular cube where i hide all my id columns from client tools.

Exemple : Table  Country

• Id : Hidden from Client tool
• Name

Then i'am running the following query 

EVALUATE SUMMARIZECOLUMNS('Country'[Id],'Country'[Name])

In ssms, query is running fine but in ssrs, i have error 'Country'[Id] object was not found. 

Iam confused, with a molap cube, i was able to query hidden columns in ssrs, i can't with tabular ? I need id's to make cascading datasets.

Thanks for your help.
