Dashboard lists like this are limited (by our core IBM platform) to a maximum of 9,999 records.  Certain analysis features that count and display summary information are able to deal with much higher quantities of records, of course, but any program that lists records one after the other, the way these dashboards do (it's sometimes referred to as a "subfile"), cannot accommodate more than 9,999 individual items in the display.  That's one of the reasons we include so many filters so you can get the list to a manageable size (since after all, who wants to press the page down key 500 times?)
