title: Access Crystal Subreport without displaying it
body: <p>In Crystal Reports 2016, I have set up a sub report and parent report.</p>
  
  <p>The sub report holds the raw data and does some calculation</p>
  
  <p>My parent report should then be a summary and additional calculations of the sub report, without displaying the full raw data which is overwhelming for the user.</p>
  
  <p>However, I cannot find a way to link the variables / data to the parent report, without also displaying all of the data.</p>
  
  <p>Is there a way to hide sub reports while maintaining access to the data - or an easier way to achieve what I am after?</p>
  
  <p>Thanks in advance.</p>
