You will get report window where you can select a preview.

You can use 'REPORT.RUNMODAL' or <report variable>.RUNMODAL. Check help on these two options.

It is not possible to run a report in preview mode directly from C/AL.
You have to show the request form.

REPORT.RUNMODAL(ReportID,TRUE,FALSE,Record);
// or
Report4711.USEREQUESTFORM(TRUE);
Report4711.RUNMODAL;

If the report should never be printed, use following code in the OnPreReport section:

IF NOT CurrReport.PREVIEW THEN
  ERROR('This Report must be started in Preview mode!');

Note: If you choose "SaveAsHTML" or "SaveAsXML", CurrReport.PREVIEW will be true!
