Mask Data Based on Dynamic Slicer Selection

[brabby_dabby]

Hello,

I have some data in a 'raw_data' table that has Customer information:

Name	Month	Incidence
Bill	1	.98
Bill	2	.96
Bob	1	.88
Bob	2	.81
Brian	1	.91
Brian	2	.82

And I have another table that creates an Alias:

Name	Alias
Bill	Customer 1
Bob	Customer 2
Brian	Customer 3

My goal is to build a dashboard that has a slicer in which I am able to select a name. So, if I select 'Bob' in the slicer, then the dashboard will mask all other names to the 'Alias'[Alias] value so Bill will show up as 'Customer 2' and Brian as 'Customer 3'.

I've seen articles that show me how to anonymize data. But I only want to partially anonymize because I want to see the name I select, but the alias for the other names. And I don't think I want row level security because I want to see all the data, but just mask it based on which slicer I select.

Any help would be greatly appreciated.

Hi @brabby_dabby ,

Please check if this is what you want:

1. Add an Index column into "Customer" table to show all rows in the table visual.

2. Don't create active relationships between "Cusomer" and "Alias" table.

3. Create a measure.

Measure =
IF (
    MAX ( Customer[Name] ) = SELECTEDVALUE ( Alias[Name] ),
    SELECTEDVALUE ( Alias[Name] ),
    LOOKUPVALUE ( Alias[Alias], Alias[Name], MAX ( Customer[Name] ) )
)

4. Result:

Best Regards,
