Connect to data flow as an external user from the Tenant using Power BI Desktop

[Joel-CG]

I want to let an user connect to a data flow from an external organization and then use that data flow in Power BI Desktop and allow him to work with that data. I know there is a preview option to allow users to connect to semantic models after inviting the user to the Tenant using Microsoft Entra B2B.

Is there a way to achieve this?

Hi @Joel-CG ,

Just as you said, you need to invite external users into the organization before you can use the organization's data flow as a guest user.
Make sure you enable the Invite external users to your organization feature in the Power BI admin portal before inviting guest users. And if you want to enter Power BI admin portal, you need to have the Global Administrator role.
And then, even when this option is enabled, the user must be granted the Guest Inviter role in Microsoft Entra ID to invite guest users. You must be assigned the User Administrator role or Global Administrator role to invite people.

You can find detailed invitation steps and restrictions in this document:

Once the external user has been successfully invited and has accepted the invitation, they can access the dataflow in Power BI Desktop. They should use the Power BI dataflows option in the Get Data dropdown. It's important to note that the Power BI dataflows connector uses a different set of credentials than the current logged-in user, which supports multi-tenant users.

Hi @Anonymous ,

I tried this solution, and it worked on my machine. I logged in with the account that was a guest on the other tenant on the Power BI Desktop, and I was able to only see the external data of my domain. 

However, when the user logged in with the same account on his Power BI Desktop, he was only able to see his work areas and not the external ones. I'm guessing it has something to do with the domain I'm currently in, but I don't know how to change it in PowerBI or why, when I logged in to my computer, I was able to see just the external and his data with the same account.

Thank you in advance,
Joel
