Error in refreshing data in Power BI

Hi Analitika ,

 

Please make sure whether you could refresh your report in Power BI Desktop. 

 

Then as Hariharan_R mentioned, your data source is an Excel in local, please check whether your gateway are the latest version and check whether you have configured your gateway correctly.

 

This problem may be also caused by different privacy level settings in Power BI Desktop and Power BI Service. Make sure you have the same privacy level security:

 

In Power BI Desktop:

 

Options and Settings --> Data Source Settings

For every Datasource: -->  Edit Permissions

Set Privacy Level: e.g. „Organizational“

 

Power BI Service:

 

Datasets --> (Choose you Datasets which does not update properly) --> settings --> Gateway Connection --> Actions --> (expand you cluster to show all Data Sources) --> (Choose relevant Datasource) --> Advanced Settings --> Privacy setting --> set same level (e.g. „Organizational) as in Power BI Desktop

 

Here is a blog with similar problem like yours, you may refer to it.
