Enabling the "Allow external guest users to edit and manage content in the organization" feature in Power BI will allow external Azure AD B2B guests to edit and manage content in the organization, including apps, dashboards, and reports. However, it does not allow external guests to access the organization's data sources.
If you want to share a data source with an external guest, you will need to create a copy of the data source and share that copy with the guest. To do this, you can use Power BI's sharing feature, which allows you to share individual dashboards or reports with specific users or groups.
To share a data source with a guest, follow these steps:
- Navigate to the workspace that contains the data source you want to share.
- Click on the "Datasets" tab.
- Click on the "..." menu next to the data source you want to share and select "Settings".
- In the "Settings" pane, click on the "Security" tab.
- Click on "Add user" and enter the guest user's email address.
- Select the appropriate role for the guest user (e.g. "Can View" or "Can Edit").
- Click on "Add".
Once you've shared the data source with the guest, they should be able to access it using their own credentials. However, they will not be able to refresh the data or make changes to the original data source. If they need to make changes, they will need to create their own copy of the data source and make the necessary changes there.
