If your report is empty and you receive the 'There is no data for this chart' message, there are a few reasons for this, including:
The data is being filtered in a way that no data is returning. You might need to edit your report and modify the filters.
The data might require access to the Security and Audit Logs that may not have been configured. Check your 365 Analytics settings.
The data has not been collected as the data collection needs to be authorized.
You may need to reauthorize your tenant. For information, see ?
If you have completed these steps and still have the notification, or the report is empty, for assistance.
