Schedule export of reports and dashboards
By scheduling the export of a report or dashboard, you configure it to run and then export it at the specified schedule. You can schedule export for saved reports and dashboards. To schedule the export of a report or a dashboard template you must generate and save its instance that can run on your prescribed schedule.
Note:
Exporting data is limited to the first 20,000 rows. Reports longer than 20,000 rows are truncated when exported. The report output (PDF, HTML, CSV, etc.) displays the message "Data in this report has been truncated."
