Report Slow To Refresh When Scheduled/ Fast When Manually Refreshed

[IamTDR]

Hi
As the topic says, I have a BI report that if I manually refresh, takes about a few seconds to refresh.  However, the report is sent to refresh automatically daily and this takes about 18 minutes.

Why such a big difference?  Is it due to a bottleneck of other reports running at the same time?

Hi @IamTDR 

Yes it can be because it is a scheduled refresh there are a lot of other datasets being refreshed at the same time (because with Power BI Pro it is using shared resources)
