Error while creating report (loading data) from Sharepoint Excel file

[Hateam]

Hi,

we have a problem while loading data to the simple report in PowerBI web app.

The Excel file is stored on Sharepoint, all permissions are granted and checked. The same file can be uploaded to the workspace, however there is a credential error while creating report.

Hi @Hateam

This issue is related to authentication or how the SharePoint file path is being handled in Power BI Service.

You can check some of the things:

• Authentication Method

  • Make sure that when publishing to the Power BI Service, you’ve set the authentication method to "OAuth2" under Data source credentials.

  • Go to Settings - Datasets -Data source credentials and edit the credentials for the SharePoint data source. Re-authenticate using the correct Microsoft account that has access to the SharePoint site.

• File Path Format

  • Double-check that you're using the SharePoint Folder connector, not just a regular Web URL.

  • Once connected through the SharePoint Folder connector, use Power Query to filter down to the exact Excel file from the file list.

• Gateway 

  • If this is being refreshed through a gateway, make sure the gateway has access to SharePoint and is configured with the same credentials.

You are using an inferior connector.  Switch over to the SharePoint Folder connector, that will also fix your credentials issue.
