Calculate a blank column for users in a specific role

[SWhiteMKL]

Hello,

I am trying to determine if it is possible to show blank values in a column for useres in a specific group vs the actual data.  I know how to apply row level security but this is column level masking or not showing the data.  Since this is a standard report structure, removing the column breack the visualization.  Just wondering if others have faced tgis issue or what the oprions in PBI might be to support this.

Thanks for the help,

Steve

@SWhiteMKL ,

try OLS - https://learn.microsoft.com/en-us/fabric/security/service-admin-object-level-security?tabs=table#cre...

or 

Create a Measure for Masking: Instead of directly showing the column in your visualizations, you can create a measure that decides what data to show based on the user viewing the report. This measure uses a function called USERPRINCIPALNAME() to identify who is looking at the data.

Column Mask = 
IF(
    USERPRINCIPALNAME() IN [usermailidcolumn], 
    BLANK(), 
    [ActualColumnValue]
)

Replace [usermailidcolumn] with the emails of users who should not see the data in that column.

Replace [ActualColumnValue] with the name of the actual column you want to hide or show based on the user. Then, Instead of using the actual column in your reports and visuals, you use this measure (Column Mask) that you created. When users who are not allowed to see the data view the report, they will see blank values or nothing in that field.

• Users who are allowed to see the data will see the actual values from [Actualcolumnvalue].
• Users who are not allowed (based on their email address) will see blanks or empty fields.
