Using Dax to remove duplicates before summing up a column

Hello,

 

This is a dax query that I have used to create a measure. 

 CALCULATE(SUM(Invoice[AmountDueAUD]), Invoice[Type]="ACCREC")

The problem is that there are multiple rows with the same invoice number and each row has the same value in AmountDueAUD column. So I want to remove the duplicate invoices before summing up the AmountDueAUD column. I know I can remove the duplicates using "Remove Duplicates" option, but there are other charts in my report that require that multiple columns. So, I want to achieve removing duplicates using Dax. I tried this but didn't work:

CALCULATE(SUM(Invoice[AmountDueAUD]), DISTINCT(Invoice[InvoiceNumber]), Invoice[Type]="ACCREC")

Thank You

    You could try and remove duplicates via the Query Editor (which has an excellent function for removing duplicates)

     

    Or in DAX you could create a summary table with just the lines you need

     

    Summary Invoice Table = SUMMARIZECOLUMNS(
                'Invoice'[InvoiceNumber],
                --- Columns ---
                "AmountDueAUD",MAX('Invoice'[AmountDueAUD])
                )

      Thanks Phil_Seamark. This worked for me.

       

      I wanted to do it without having to create a new table and also I couldn't do it via Query Editor because there were other charts that relied on the duplicates.

       

      Please let me know if you come across something that solved this problem without having to create a new summary table.

        Hi bjoshi,

         

        It probably is possible to do as a measure over your original table, but it's probably not good data modelling to have the same number on repeating lines that shouldn't be there in the first place.
