title: How to do a Sub Report in SQL Server Reporting Services
body: <p>I developed a report in Reporting Services 2008 R2 that takes 3 parameters:</p>
  
  <ul>
  <li>Start Date</li>
  <li>End Date</li>
  <li>UserId (single choice from a drop down list)</li>
  </ul>
  
  <p>And produces some data from 4 different Data Sets.</p>
  
  <p>What I want to do next is allow multiple UserId choices and produce the report with one page per User. I thought I would be able to do that by using a List, and throwing all those other tables inside the list, but it doesn't let me, as it says the list has to draw data from only 1 Data Set.</p>
  
  <p>How can I accomplish that? Or do I have to do a new report and call this report from there? And how to I do that?</p>
  
  <p>Thanks.</p>
