Anyone out there know how to optionally filter a result set (optional
being the key word)? For example, in the Foodmart Sales Sample
report, I would like to optionally filter by Product Family - have the
ability to see all members at once. I tried to manually add the "all
member" to the drop down list, but that did not seem to work. Any
attempt to not select one of the 3 product families returns a null
report.

Any advice?
