Alerts each 24 hours do not work as expected

[Rodrigo_Carvalh]

My dataset is scheduled to refresh once a day at 9:30, and we have configured alerts on dashboards to be sent only once every 24 hours. The time to refresh the dataset varies a lot, so one day it may finishes at 9:50 and on the next day at 9:45. In this case we do not receive email alerts on the second day, as it refreshed before to complete 24h, which is completely unexpected!

Hi @Rodrigo_Carvalh,

As you you see here: 

When you configure a time for scheduled refresh, there can be a delay of up to one hour before it begins.

If you create a alert for the dashboard, Power BI checks to see if it's been more than an hour or more than 24 hours (depending on the option you selected) since the last alert was sent. As long as the data is past the threshold, you'll get an alert. See: Receiving alerts.

In your scenario, please double check if the data hits the threshold after data refreshed.

Yes, I configured my user so that it should receive alerts everyday, but sometimes it just does not happen, because the last aler was sent only 23 hours and 45 minutes before, which is bellow the 24 hours, and this is caused by the variation on the refresh time.

I am configuring the users to set alerts every hour, which makes then receive double alerts when I update the dataset for maintanance.

Is there any update to this submission? 

I have the same problem. As I understand what the functionality should be: Once selected, the alert should only send one iteration after the dataset is refreshed.

Context

• The dataset refrshed between 7:30- 7:36 AM EST.
• I had "At most once an hour," selected.
• Alerts were sent at 7:36 AM EST as well as 9:22 AM EST
• The dataset had no other refresh during this timeframe
