Fixing Power BI Connection Issues with SharePoint Credentials

Encountering errors when connecting Power BI to SharePoint can be frustrating, especially when receiving messages regarding unsupported credential types. This guide provides comprehensive solutions to this common issue faced by Power BI users.

Solutions for Power BI Credential Errors

Step 1: Modify Data Source Permissions

Start by adjusting the permissions for your data sources. Adding Microsoft Account credentials can often resolve the access issue. Here’s how:

  1. Open Power BI Desktop and go to Options and settings, then select Data Source Settings.
  2. Select SharePoint from the list you wish to modify.
  3. Click on Edit Permissions > Edit.
  4. Input your Microsoft Account credentials and click Ok.

Pro Tip: Always ensure your user permissions are up-to-date and relevant to your Power BI access needs.

Step 2: Clear Cache and Update Password

If the initial step does not work, try clearing the cache of Power BI and ensure that your password is updated. Follow these steps to clear the cache:

  1. Launch Power BI Desktop.
  2. Go to File.
  3. Select Options and settings > Options.
  4. Under the Global section, pick the Data Load tab.
  5. Finally, click Clear Cache from the Data Cache Management Options.

The cache removal can help refresh your connection settings. If you still have issues, consult your IT admin about updating your password.

Step 3: Set Default Browser for Authentication

If you suspect a problem with browser authentication, ensure that Power BI uses your current default browser. Perform the following steps:

  1. In Power BI Desktop, go to File.
  2. Click on Options and settings.
  3. Under Global, navigate to Security.
  4. Modify the Authentication Browser setting to Use my default browser and click Ok.

Step 4: Refresh Data Source Permissions

Datasets can become corrupted and require refreshing. Here’s how to clear the permissions:

  1. In Power BI Desktop, click on File > Options and settings.
  2. Go to Data source settings > Global Permissions.
  3. Select SharePoint and click Clear Permissions.
  4. After this, close the settings window.

Re-enter your credentials, and this should resolve any permissions-related issues.

Step 5: Utilize OData Feed for Connection

If standard connections aren’t functioning, try connecting using an OData feed:

  1. Within Power BI, select Get Data from the Home section.
  2. Choose OData Feed.
  3. Input the SharePoint list URL into the text box in this format: http://URL/Location/DataListicles.svc.
  4. Select the authentication method and click Connect.

Step 6: Reach Out to Power BI Support

Should all else fail, it’s time to contact the Power BI Support team. Create a ticket by visiting support.fabric.microsoft.com, and they will assist you in resolving the issue.

Summary

Resolving the unsupported credential type issue in Power BI when connecting to SharePoint can typically be addressed through multiple approaches, including editing permissions, clearing cache, or using alternate methods like OData feeds. If these solutions do not yield results, contacting Power BI Support is recommended.

Conclusion

Addressing connectivity issues between Power BI and SharePoint requires systematic troubleshooting. Employing the outlined steps will significantly increase your chances of restoring functionality and optimizing workflow.
