What I am doing with the DAX below is to only show the concatenation of values if a value is filtered. If nothing is filtered (Selected) then display text to show that nothing has been selected, otherwise display in a concatenation what has been selected.

NOTE: If you individually have to select each item, it is still being filtered so it will show all the values concatenated.

 

  • What is happening above with the Variable called “ConCat” is where I am concatenating the items from the ‘PowerBI Audit Log’ table and using the [User] column.
  • Then in the next Variable called “IsItFiltered” I am using the IF and ISFILTERED DAX function to evaluate if the [User] column is being filtered.
    • If it is being filtered then return the previous Variable called “ConCat” otherwise return “No Users Selected”
  • And the final piece is where I am returning the output from the IsItFiltered Variable
  • This is what it looks like when No users are selected
  • And then when two users are selected

As always if there are any questions please leave them in the comments below.
