title: Cognos Dynamic Filtering
body: <p>I searched all over the internet but couldnt find an answer.
  I want to create 
  1. a radio button with two options A, B (which are supposedly two columns in the database with "date" datatype) and
  2. a date prompt 
  Now if the user selects option A with a date range(in the date prompt) the data should be filtered on A
  if the user selects option B with a date range(in the date prompt) the data should be filtered on B</p>
