Cannot load data from dataflow to Power Bi Desktop

Hi qsong ,

Please check how much memory do you have and how much space you have used.

By my research, sometime this may be a temporary error. You could have a reference of these similar threads which have been solved : case1, case2, case3.

You may need to improve the dataflow performance: https://community.powerbi.com/t5/Service/SQLServer-performace-issue-will-dataflows-help/td-p/783770.

Or use incremental refresh for dataflow, see more detail:https://docs.microsoft.com/en-us/power-bi/service-dataflows-incremental-refresh.

After creating the new dataflow, you may refresh the Dataflow on Power BI Service to make data loaded into the entity. Then, click the "Refresh" button in "Navigator" pane when use Power BI dataflows connector in Power BI Desktop . If still no data is shown, please clear permissions under "Data Source settings", and establish the connection to dataflow again.

Best Regards,

Amy
