DataFormat.Error when refreshing data in Power BI Service

Hi everyone, 

 

I am doing a report which carries many data sources (access file, excel files and D365CRM). The report is done in Power BI Desktop and refresh without any error. I uploaded the report to PBI Service and setup the Data Gateway, all works well as below

Then I set up refresh schedule and try to refresh the data. But I got the failure when refreshing with below notification

As I understanding the error alert a problem from access file but I checked once again the file in Power BI Desktop, try to fix all the format and refresh in Power BI Desktop. No any errors there. I uploaded again new saved file to same workpace, and set up again the data gateway. When I refresh, it still appears. 

Could you please help me in this case? I do not know where to fix this problem. 

 

Thanks so much

Thu

Hi  @ThuJa23 ,

The following information was obtained from an internal search:

“Microsoft.PowerBI.DataMovement.Pipeline.Diagnostics.MashupDataAccessValueException: Mashup expression evaluation error.’

You can try the following:

Do you have a calculated table in your composite model, and if so, you can delete it on refresh.

You can export the additional logging mashup file in the gateway to see if there is a problem
