Hi , @andleebRaja 

Based on your case issue description, you seems to configure the dynamic RLS with the UPN used for the DAX expression that define the RLS roles,  the RLS tested successfully in the "Test as role" but displayed blank for the external users, right? I think the root cause for your issue reason may like this: when the external users are added to your organization as a guest user, their actual UPN that is used to access your Power BI tenant is displayed with the string "#EXT#@" in the middle like this:

So when you added them to your RLS user table with their original UPN, you can successfully test them in the "Test as role" but it displayed blank for the external users when they actually use the UPN with the string "#EXT#@" in the middle to access your Power BI tenant, so you can try add them into the workspace as a "Viewer" role and check their specific UPN to update them in the user table and make the test again, thanks in advance!

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
