Use connection parameter in MDX

[Arno69]

Hello,
i try to use a connection parameter in MDX Role. (see attachment)
Does anybody succeeded ?

I try this syntax in Member Grant :
Autorite.[Parameter("pDep")]
or Autorite.[${pDep}]
or Autorite.[%{pDep}]
or Autorite.[@pDep]





Thanks for any help.

Regards,
Arnaud
