Filtering a Filter
What would be the easiest or best way to filter the options presented by a filter control?
For example, suppose that I create a query using HoleFoods that uses a named filter to filter the product categories according to some criteria. When I display the query on the dashboard, I would like to provide a filter control that will allow users to further constrain the product categories. However, a simple filter control will display all the product categories available in the cube many of which are irrelevant to the current query.
Thanks for your help!
