Hi @Anonymous ,

 

Try the following measure:

 

Users for product A =
COUNTROWS (
    FILTER (
        ADDCOLUMNS (
            SUMMARIZE (
                ALL ( Sales[Product]; Sales[User ID] );
                Sales[Product];
                Sales[User ID]
            );
            "Count"; CALCULATE (
                DISTINCTCOUNT ( Sales[Product] );
                ALLEXCEPT ( Sales; Sales[User ID] )
            )
        );
        [Count] = 1
            && Sales[Product] = "A"
    )
)

Hi @Anonymous 

You may try below measure:

UniqueCount =
VAR _table =
    SUMMARIZE ( Sales, Sales[User ID], "Count", DISTINCTCOUNT ( Sales[Product] ) )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( Sales[User ID] ),
        FILTER ( _table, [Count] = 1 && MAX ( Sales[Product] ) = "A" )
    )

Hi @Anonymous ,

 

You have two option to make this:

Assuming you are making this on a card visual (but works for other type of visuals

Option 1:

  • Place the User on the card visual
  • Select the summarization Count (distinct)
  • Place the Product on the filter for the visual
  • Select Product A on the filter

Option 2:

  • Create a measure with the following code:
Users for product A = CALCULATE(DISTINCTCOUNT(Sales[Users]);Sales[Product] = "A")

 

Depending on the way you want to show the information both have advantages and disavantages.

Thanks @MFelix ,

 

I was not clear in my original answer I have updated the original question to better address my need. Your current solutions will count all Users with product "A". I only want the unique user count for users who purchased only Product "A" and nothing else. 

 

Thanks. 

Hi @Anonymous ,

 

Try the following measure:

 

Users for product A =
COUNTROWS (
    FILTER (
        ADDCOLUMNS (
            SUMMARIZE (
                ALL ( Sales[Product]; Sales[User ID] );
                Sales[Product];
                Sales[User ID]
            );
            "Count"; CALCULATE (
                DISTINCTCOUNT ( Sales[Product] );
                ALLEXCEPT ( Sales; Sales[User ID] )
            )
        );
        [Count] = 1
            && Sales[Product] = "A"
    )
)
