How to pause a scheduled report
To start, ensure you're on the Scheduled tab of the report page. Then, click the name of the report in question to open the editor.
At the top of the screen, click Schedule. This will open the Schedule settings for your report.
Then, choose "Paused" in the "Frequency" drop down and click "Save".
The same "Paused" option is available when setting up new scheduled reports.
