Reprt builder expression for calculation based on distinct values in a column

Hi,

 

I have a power BI report builder which has duplicated rows (column A) as below. I need to calculate sum of column B based on unique values in column A. Please let me know the report builder expression.

 

Column AColumn B
PartA150
PartB100
PartA150
PartB100
PartC200
PartC200

 

I need the expression which would calculate sum of PartA + PartB + PartC = 150+100+200 = 450

 

Thanks to assist.

 

Regards,

Muralidhar

    A simple measure should do:

    Measure = SUMX(SUMMARIZE('Table',[Column A],'Table'[Column B]),[Column B])
     
    And if there are always 2 repeated values, you can also use:
    Measure = SUMX(DISTINCT('Table'[Column B]),[Column B])

      Anonymous It did work when I tried it in the power BI desktop where I have built the dataset. But, when I import this measure to the report builder report to which dataset is connected, it just gives me the first row value. Can you let me know what needs to be tweaked?

    Hi !

    Does the values in ColumnB will always be exactly same for repeted ColumnA members. How you want the calculation to work if you have have PartA with 2 distinct values in ColumnB, 150 & 120. What you want to do in this scenrio.

      Values in ColumnB will always be exactly same for repeted ColumnA members, so we can ignore the scenario of columnB having different values for a value in column A. 

      Thanks for checking!

        Hi !

        I would solve this like below;

         

        1) Create a new table using DAX;

        Go to Modelling Tab -> New Table, provide following DAX

        NewTable = SUMMARIZE(Table, Table[ColumnA], Table[ColumnB])


        Table is the name of your table, you can replace it with your table name in the formula.

         

        Now create a measure to sum column B, use following DAX

        NewSum = SUM(NewTable[ColumnB])

         

        Hope this will solve your requirement.

         

        Regards,

        Hasham
