Data-driven subscription : passing multiple values parameter

Hello,

I created a data-driven subscription for a report which contains one parameter with multiple values allowed.

If I store in a table one value (ex : [Country].[Country Code].&[USA]) and run the job, the subscription succeeds, but if I try to run it with multiple values (ex : {[Country].[Country Code].&[USA], [Country].[Country Code].&[FRA]}), it fails.

Then : how can I pass multiple values to a parameter ?

NB : I already tried to have several lines in the table (one per value), but it runs X times the subscription whereas 1 time is expected with the multiple values.

NB : I already tried to have : "{..., ...}" or "{...,...}" or "..., ..." or "...,..." (about the format in cell in the table), but nothing succeeded...

Thanks for help.
