Defining a Base Filter

• By specifying a filter when the view is created.
• By editing an existing view, and specifying/modifying the filter.
• By specifying a refined filter, then saving the view. This causes the refined filter to be added to the base filter (if one exists), creating a new base filter.

Currently, the only way to tell if there is a base filter defined for a view is to open the view wizard and look on the Filter dialog.
