data masking but need to show current user details

[Anonymous]

First of all, this is not about row level security.

Say we have sales rep and their sales data

SalesRep table:

SalesRepId, SalesRepName, MaskedSalesRepName, SalesRepEmail

1,                'Joe Smith',        'Sales Rep A',     'joesmith@gmail.com'

2,                'John Wick',        'Sales Rep B',     'Johnwick@hotmail.com'

Sales table: SalesId, SalesRepId, product, price etc

Final output (in table and bar chart)

MaskedSalesRepName, No of sales

Sales Rep A,                   12

Sales Rep B,                    5

The requirement here is to mask the Sales Rep Name in the report - which is easy to do. However, there is a problem for this approach. 

If the sales rep A login (as joesmith@gmail.com), he sees a report like this, he would not know which sales no is his own as the name is masked. Ideally he sees

MaskedSalesRepName, No of sales

Joe Smith,                     12

Sales Rep B,                    5

So while he see everyone else No of sales without knowing their names, he also sees his own sales number. 

Hope this makes sense. 

Thanks in advance.

You might need a measure like this

Masked Measure =
if( max(Table[SalesRepEmail]) =USERPRINCIPALNAME() = ,max(Table[SalesRepName]),"Other"))

Masked Measure =
IF( max(Table[SalesRepEmail]) =USERPRINCIPALNAME() = ,max(Table[SalesRepName]),max(Table[MaskedName]))

thanks for the quick reply. It was very helpful. Actually I have read that link before asking the question. I got stuck by trying to use the new measure as the AXIS - which is not possible. I now realised I can use masked Sales Rep name as the AXIS. In order to know which is the current user, all I need is to the set the visual filter to "current user is not blank" (current user is the new measure created in the link)

@Anonymous  - Well, you could potentially user USERPRINCIPALNAME like:

MaskedSalesRepName Measure =
  IF(USERPRINCIPALNAME() = MAX([SalesRepEmail]),MAX([SalesRepName]),MAX([MaskedSalesRepName]))

Might work.
