Use of TOPN in a measure

[smpa01]

Hi,

My source data is following

Name	Value
P1	100
P2	200
P3	300
P4	400
P5	500
P6	600

From here, I want to come here

Name	Value
P3	300
P1	100
P2	200

which can be achieved by creating a

newTable = TOPN(3,'Fact','Fact'[Name],ASC)

Now, I want to acheive the following by using it inside a measure and I could not make it to work.

Can someone please point me to the correct direction.

Thank you in advance.

topn = SUMX(TOPN(3,'Fact','Fact'[Name],ASC),'Fact'[Value])

Hi @smpa01 ,

Try this measure

rank =
SUMX (
    FILTER (
        'Fact',
        RANKX ( ALL ( 'Fact' ), CALCULATE ( MAX ( 'Fact'[Name] ) ),, ASC, DENSE ) <= 3
    ),
    [Value]
)

You can check more details from here.

@Anonymous  thanks for looking into this. I know how to get to the desired result using RANKX. I was trying to see if I can get there using TOPN.

@smpa01 , Try if this measure can help

topn = SUMX(filter('Fact', 'Fact'[Name] in TOPN(3,'Fact','Fact'[Name],ASC)),'Fact'[Value])
