How to make dynamic table/column, based on Username

Hi,

 

I'm trying to create a calculated column to my table, which contains the value of another existing column, if the current user's username is contained in a third column containing the allowed users' usernames, and if it doesn't, it shows a given text.

 

So my table should look like this, if user1@email.com views it:

table1

column1allowed userscalculated
xyzuser1@email.comxyz
yyyuser2@email.comaccess denied

 

The point is, I want to show the value of a column based on the allowed users column and the logged in user.

 

My current DAX code looks like this:

Calculated =
IF(
CONTAINSSTRING(SELECTCOLUMNS( table1,"Allowed",[Allowed users]),USERPRINCIPALNAME())
, SELECTCOLUMNS( table1,"Szöveg",[Column1]),"access denied"
)
 
This is not working because USERPRINCIPALNAME() can't be used in calculated columns.
 
Are there any workarounds to this problem?
 
Many thanks!

@Anonymous , USERPRINCIPALNAME() can be used in measure not column

 

So you can have like

 

maxx(table1 , IF(
CONTAINSSTRING(SELECTCOLUMNS( table1,"Allowed",[Allowed users]),USERPRINCIPALNAME())
, SELECTCOLUMNS( table1,"Szöveg",[Column1]),"access denied"
)

 

and use in aline level visual
