    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.
