Sum for the first occurrence

[ermak]

Hello! Please help me sum up the price only for the first hits within the sessions. So that 3.33 comes out, not 16.65.

Hi @ermak ,

You could try this measure.

Sum for the first occurrence =
CALCULATE (
    SUM ( 'Table'[Cost] ),
    FILTER (
        ALL ( 'Table' ),
        [HitID]
            = CALCULATE (
                FIRSTNONBLANK ( 'Table'[HitID], [HitID] ),
                ALLEXCEPT ( 'Table', 'Table'[SessionID] )
            )
    )
)

The result is this.

You can check more details from here.

@ermak , I am assuming HitId is the minimum session can be found

calculate( Sum(Table[Cost]), filter( Table,Table[HitId] = min(Table[HitID])), allexcept(Table, Table[SessionID]))
