Calculate sum with a distinct filter

[DGodQc]

Hello community,

I have problems calculating an availability % for my production. Here is my formula at the moment:

Availability = (sum(V_COMB_PROD_CRW1[PROD_HRS])/((sum(V_COMB_PROD_CRW1[PROD_HRS])+sum(V_COMB_PROD_CRW1[TOTAL_DOWNTIME_HRS]))-sum(V_COMB_PROD_CRW1[PLANNED_DOWN_TIME])))*100

Problem is:  i need to calculate those results, but only one time for each dayprod_ID. I've tried SUMX with distinct formulas, but i can't get the right way to do it.

Is there a more advanced user that can give me a hint??

Thanks,

Dany

Hi @DGodQc ,

You could add an index column with query editor. Then use RANKX() function to create a rank column.

rank =
RANKX (
    FILTER ( testTable, testTable[ID] = EARLIER ( testTable[ID] ) ),
    testTable[Index],
    ,
    ASC,
    DENSE
)

Then sum the value where [rank]=1.

Measure =
CALCULATE (
    SUM ( testTable[value] ),
    testTable[rank] = 1,
    ALLEXCEPT ( testTable, testTable[ID] )
)

It seems very similar to the sum of the Avg problem. Please refer
