    <p>I have several Birt Reports that I am trying to set up to run on a cron job that will email pdfs of the reports every morning. Everything is working fine as far as the generation and emailing goes; the only issue I am stuck with is this: if there is nothing to report, a pdf with just the report title is generated and emailed (a blank report, basically). I'd like to stop this report from being generated at all, so i can skip the emailing, if the pdf file does not exist.</p> <p>I have been all over Google for two days now, and the closest I can find is this: <a href="http://www.eclipse.org/forums/index.php/t/458779/" rel="nofollow">http://www.eclipse.org/forums/index.php/t/458779/</a> in which someone was trying to solve a similar problem and received a push in the right direction, but not a complete solution.</p> <p>It appears as if this can be done during the <code>beforerender</code> script... but how? I know I need to:</p> <ol> <li><p>set a persistent global variable in the <code>oncreate</code> if there is indeed data to report.</p></li> <li><p>get the persistent global variable in the <code>beforerender</code> script.</p></li> <li><p>send the magic <code>don't generate report</code> command.</p></li> </ol> <p>I'm doing all of generating and emailing from a php script, not Java, so I can't send commands like <code>IEngineTask.cancel()</code> (or can I???)</p> <p>Yes, I know I can make a row in the report that says "No data to report", but that's not what my users want.</p> <p>And yes, I could query the database outside of the report to determine if there is valid data to report or not, but i'd prefer not to.</p> <p>And maybe I could even open and read the pdf, programmatically to see if there is anything there, but that sounds like more of a hassle than it's worth...</p> <p>So, how do I do this?</p> <p>Thanks. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
