Users masked in classic Usage Report but not in new Usage Report

[Martin_D]

Hi,
I have set up my tenant to mask user names in usage matrics reports for certain users.

In the classic usage metrics report it works:

In the new usage metrics reports, there are the clear names, which is wrong (the screenshots report on the same used report at the same day):

How to fix this (how to explain that user masking is different in the two reports at all)?

Kind regards,

Martin

Hi @Martin_D ,

Thanks for reaching out to the Microsoft fabric community forum.

Based on the screenshot you shared, here are a few workarounds:

 Check Fabric Admin Privacy Settings

Go to Microsoft 365 Admin Center → Microsoft Fabric Settings.

Review privacy and telemetry configurations.

Ensure user-level usage data visibility is limited to necessary roles (e.g., admins only).

Verify Activity Log Access Permissions

Confirm that only approved roles can access the Activity Events dataset used in the new report.

If broad access is allowed, consider restricting report visibility or filtering data.

Mask Users in Power BI Report Logic

Clone the new report and modify it to mask names.

Use DAX to replace names with aliases:

DAX

MaskedUser = SWITCH(TRUE(),

    UserName = "user1@domain.com", "User A",

    UserName = "user2@domain.com", "User B",

    "Masked")Or apply Power Query transformations using a lookup table or anonymization logic.

  Implement Row Level Security (RLS)

Configure RLS to ensure only authorized viewers can see specific user data.

Use roles and filters to hide names based on viewer identity.

Dear @v-lgarikapat ,

Thank you for having a look at this issue.

Maybe I need to be a bit more specific about what the solution needs to look like. Actually, the solution does not need to do more than what is promised by Microsoft in the manual here: Monitor usage metrics in workspaces (preview) - Power BI | Microsoft Learn

We have set up in the Fabric tenant settings, that only for some users per-user clear names are visible and for others not, following above documentation. For the classic usage report it seems to work, as shown in the screenshot in the original post. At the same time, for the new style usage metrics report it does not seem to be effective, obviously, as you can see from the original screenshots I provided, which is a severe legal data privacy issue for us. In the documentation, I did not find a description that distinguishes between classic and new usage metrics report. The setting should configure user name anonymization to behave the same in both, classic and new usage metrics report. What am I missing here? What do I need to do so that also the new usage metrics report applies the same per-user usage metrics data anonymization settings as the classic usage metrics report - as a tenant setting, not as a workaround?

Best regards,

Martin
