Can I hide subreport

<p>I have a subreport in a Group Header that I need to run in order to get some variables and pass it back to the main report. I don&#39;t want anything from the subreport to display on the main report. I&#39;m just using it to get some variables.</p><p>If I suppress the report or the section, the main report shows the shared variable as 0. Is there a way to hide the report, but still have it run so I can get the variables?</p>
