Restriction of one dimension members based on another dimension members selection

Hi Experts,

We are on BPC10.1. EPM version 34.2.

I would like to restrict members of a dimension(account) based on the member selection of another dimension.

If I select 'Average' member for a dimension,I should see only 'BSTERMS' hierarchy for Account dimension.

I shouldn't get an option to select 'ISTERMS' node.

Like wise,if I select 'Marginal' I should get the list of 'ISTERMS' only.

Best Regards,
