If you need to create a simple data filter, use the Original filter builder in Bill Analyst. This filter uses AND/OR operators and is limited to twenty comparison rows. If you need to create filters using ALL/ANY combinations, searchable strings or up to fifty rows of criteria—use the Condition Builder tool.
New filters appear on the filter page (you may need to scroll down to see them). If you've shared a filter, there will be a notation in the shared column. You can also create (add) filters via the summary and detail tabs.
