When pointing to a SharePoint folder, the data does not refresh in PowerBI Desktop.

edit

There are several possible reasons why the data in a SharePoint folder may not refresh in Power BI Desktop. Here are some things to check:

1. Ensure that the SharePoint folder is accessible and that you have the necessary permissions to access the folder and its contents.
2. Check that the file you are trying to import is not open or in use by another program or user, which can prevent the data from refreshing.
3. Verify that the connection settings in the Power BI Desktop File menu are correctly configured for your SharePoint site, including the site URL, authentication method, and credentials.
4. Try manually refreshing the data in Power BI Desktop by selecting the Refresh button in the Home tab or by pressing Ctrl+Alt+F5. Check the progress of the refresh to see if any errors or warnings are occurring.
5. Check the settings in the Power Query Editor to ensure that the data source is correctly configured and that any filtering, sorting, or transformations are correctly applied. Look for any errors or warnings in the Applied Steps pane.
6. Make sure that any related tables or queries are also refreshed, as changes in one table may affect the data in others. Use the Manage Relationships dialog box to link tables together if needed.
7. Consider using Power BI Gateway to automate the refresh process and ensure that data is always up-to-date. Configure the gateway to access your SharePoint folder and set up a schedule for automatic refreshes.
