Dataflow keeps failing refresh

Hi Anonymous 

We would need more information to help you. Unfortunately, those ideas are of no value for us to help in troubleshoot.

I have started to see this too.  I believe the issues I am running into result from using a Power BI Pro workspace with data flows that combine multiple sources tables (merges or appending tables).

Thanks for the reply from GilbertQ and PDDP.

Hi Anonymous ,

You can think about things in terms of the following, including this scenario PPDDP mentioned.

Try to check the refresh failure history how a dataflow refresh operation performs, and review the Refresh History for the dataflow by navigating to Dataflow > Settings > Refresh History. 

The metrics for refreshing historical information can be viewed at this link:Understand and optimize dataflows refresh - Power BI | Microsoft Learn

Troubleshoot refresh scenarios - Power BI | Microsoft Learn.This link provides some ideas including checking  your gateway version. Update your gateway to the latest version, or a supported version to resolve this issue.
