title: [SSRS]: Is there a way to return a flag indicating that the report has no data?
body: <p>I am using SSRS for reporting and I am generating them in an ASP.NET Core application using <a href="https://docs.microsoft.com/en-us/dotnet/api/reportexecution2005.reportexecutionservice.render2?view=sqlserver-2016" rel="nofollow noreferrer">ReportExecutionService</a>.
  I have a background job that runs daily in the backend to generate the report and send it via email to the users.</p>
  <p>However, sometimes when we don't have data, the generated report will be blank, So, <strong>I am trying to find an indicator in case of blank report, so that I won't send it to users in that case.</strong></p>
  <p>Is there such an indicator returned by SSRS in case of empty reports? If not, is there a simple way to add one?</p>
  <p>Thanks,</p>
