Data Refresh Error

[Anonymous]

The scheduled data refresh for a certain report published in the PowerBI Service keeps failing with this error:  "An error occurred while processing the data in the dataset.  The CancellationTokenSource has been disposed.. The exception was raised by the IDataReader interface. Table: cmv_Sales."  There are no other details, and I can't seem to find a cause/solution online.  Has anybody seen that type of error before?  Thank you very much!

Hi @Anonymous,

There should be RequestID, Time and ClusterURI information display when you check details in Refresh History. Please share these information for us. 

You can download the report from Power BI service and open it in Power BI desktop, click Refresh button to see if the refresh can be successful. 

Best Regards,
