When assigning parameters to a report is there a way to make at least one mandatory?
Take an example where you have 3 input parameter drop downs, they all default to the value "All". If I run a report with it set like this then it will produce too much data. What I would like to is make a rule forcing the users to make sure at least one of the parameters is something other than "All".
Update: One of the parameters my turn into a number of checkboxes
