Hi  all,

 

Please check whether the data amount refreshed quite large so it caused the long time refresh. If your model is very simple, please try to refresh your dataflow with on-demand refresh to see whether you will have same issue or whether this issue is happening at a relative fixed time.

If your dataflow refresh issue is not caused the above reasons and you are a Pro user, please consider getting direct help from the technical team of Microsoft by support ticket. They will have a remote session with you to troubleshoot on this issue.

For how to create a support ticket, please refer to this blog: https://community.powerbi.com/t5/Community-Blog/How-to-create-a-support-ticket-in-Power-BI/ba-p/6830...

It has been brutally slow today. This renders data flow creation useless.

We have the same issue and I'm pretty sure this is tied to the support issue on the front page.  Only Premium dataflows aren't refreshing and our tenant is in the North Central doesn't make it better but at least we know it's not us.

A dataflow that gets run on a MSSQL source that returns 4M+ rows normally takes about 4-6 minutes to refresh on an incremental refresh, has been refreshing for 15+ hours.

 

Can you please please fix the issue? It is simply making me go crazy as I can't deliver it to client. 

 

PLEASE HELP ASAP.

That the same issue which lasted for weeks in May 2021 and MS was silent that time as well. It is sad...

I have a massive dataflow dependency to the overall reporting (60 dataflows) all of which have failed on schedule and does not refresh on-demand as well.

 

Please fix ASAP

I am also having the same issue with dataflows. The refresh is not working and I am also not able to create a new dataflow.  Getting the below error.

If I am trying to edit an existing dataflow it is getting stuck on "Validating queries" screen. 

This issue need to be fixed ASAP.
