Variable Top N depending on Column Conditions

[NiMa]

Hi Everyone,

I want to create a DAX which gives following result :

So based on the "total" I want to find out "Top 3 brand" for "Category A and B" and "Top 1 Brand" for "Category C".

I am able to show top 3 Brands across all categories but facing difficulty with variable Top selection based on Category.

Please help.

Thanks Hariharan_R. This measure is absolutely correct. But i have one more doubt for the same. 

How to show multiple Categories in this DAX where i need this condition of variable Top N . For eg,

I have Category D and E as well along with C where this filteration of top N is different as compared to Category A and B.

Thanks.

Hi,

You can use below measure.

Top 3 = 
VAR _N = IF(MIN('Table'[Category])="C",2,3)
VAR Top3 =
    CALCULATETABLE (
        GENERATE (
            VALUES ('Table'[Category] ),
            TOPN (
                _N,
                CALCULATETABLE ( VALUES ('Table'[Brand] ) ),
                [Sales]
            )
        ),
        ALLSELECTED()
    )
RETURN
    CALCULATE (
        1 * ( NOT ISEMPTY ( 'Table' ) ),
        KEEPFILTERS ( Top3 )
    )

Sample Data

Thanks

Hi,

If you have more values then try use disconnected table with the TOPN values otherwise try the below one.

Top 3 = 
VAR _N = 
SWITCH(TRUE(), MIN('Table'[Category])="C",2,MIN('Table'[Category])="D",1,MIN('Table'[Category])="E",1,3)
VAR Top3 =
    CALCULATETABLE (
        GENERATE (
            VALUES ('Table'[Category] ),
            TOPN (
                _N,
                CALCULATETABLE ( VALUES ('Table'[Brand] ) ),
                [Sales]
            )
        ),
        ALLSELECTED()
    )
RETURN
    CALCULATE (
        1 * ( NOT ISEMPTY ( 'Table' ) ),
        KEEPFILTERS ( Top3 )
    )

Thanks

Hi @Anonymous 

You can remove _N with 5 like below.

CALCULATETABLE (
        GENERATE (
            VALUES ('Table'[Category] ),
            TOPN (
                5,
                CALCULATETABLE ( VALUES ('Table'[Brand] ) ),
                [Sales]
            )
        ),
        ALLSELECTED()
    )
RETURN
    CALCULATE (
        1 * ( NOT ISEMPTY ( 'Table' ) ),
        KEEPFILTERS ( Top3 )
    )

Thanks

Hari
