title: How do you prevent a Cognos report from allowing you to filter data items that don't exist in the report?
body: <p>I have a list report, and it pulls from a query subject that contains the following products: a, b, c, d, e.  However, the report query contains a filter that filters for a, b, c.  </p>
  
  <p>Once you execute the report in HTML it displays products a through c as expected. 
   The issue is that once you click on the product column, create filter, the filter shows values a through e instead of a through c.  Do you know how to fix this, so that you can't filter on products that don't exist in the report?</p>
