Sending report to users by email only if report returns data

 Hi,

I have generated a report with the past due invoices. This report is executed and sent every night to the financial manager. Some days this report has data and some days it doesn't. When there is no data the report is sent by email anyway, Is there a way to stop this.

The desired behaviour is that the report is sent by email only if the report returns data. This way the finance manager won't receive empty emails. Is this possible bi BIP 11g?

Thanks in advanced.
