title: Running a report for the previous week
body: <p>Let me preface by saying that I am a noob to <em>JasperReports</em>, so I apologize if there is an obvious answer to my question. I have an existing <em>JR</em> report that runs manually on one month intervals. I can open the report up, select an input month from the dropdown, and it will feed me back data for that month.</p>
  
  <p>In addition to manual monthly runs, I want this report to to run on a weekly schedule and return data for the past 7 days only.</p>
  
  <p>I see that I can set up a scheduled run pretty easily, but to me it looks like the input is fixed, and I will only get the same week back, week after week.</p>
  
  <p>I am using <em>iReport 4.5</em>.</p>
  
  <p>I feel like the easiest solution will be to duplicate this report, and make the new report run weekly functions only (I'll never do a manual run for weekly, only monthly). But after going through some of the tutorials online, I don't see how to make a report run for the previous seven days only.</p>
