Issues with invitations to a dynamic RLS dashboard to users from external tenant

Hi Anonymous,

#1. To share a dashboard with RLS applied, we need to add the guest users in AAD ahead of time and assigning them to the security roles before sharing the content. For more information, see this whitepaper: https://aka.ms/powerbi-b2b-whitepaper

#2. This scenario is mentioned in the whitepaper shared in #1. It's recommended to use planned invites. 

#3. As I tested, both planned invites and ad-hoc invites, the external users will be prompted to accept the invitation. 

#4. Not sure what you mean about "db". Would you please clarify it? 

#5. When we type the user in RLS role, it will prompt corresponding highlighted list for us to choose, after click on the specified user, the user is ented in the box. Then you can type another email address without any comma or semi-colon separate. 

From the screenshot, I guess the email you want to add is a external email address which can't be recognized. You can add this guest user in AAD as mentioned above and add it as a member again. 

#6. Based on my research, it's not supported to do it currently.
