    HI Maghol

     

    Please try this one

     

    TEST =
VAR TheDate =
    DATE ( 2018, 12, 5 )
RETURN
    SUMMARIZE (
        Blad1,
        Blad1[order_id],
        "The_Qty", CALCULATE (
            SUM ( Blad1[qty] ),
            TOPN (
                1,
                FILTER ( VALUES ( Blad1[log_date] ), Blad1[log_date] <= TheDate ),
                [log_date], DESC
            )
        )
    )

Thanks for the reply but I get an error: "A date column containing duplicate dates was specified in the call to function 'LASTDATE'. This is not supported".

 

Log_date is in dateformat,

HI Maghol

 

Did you see the attached file??

 

Did you use the formula as a Calculated TABLE???

    No, I tried it as calculated table on my on data. Problem is that there are many entries with the same date for one order_id in log_date, only timestamp seperates them. Think I need to use MAX() instead of LASTDATE()?

      It shouldn't make a difference...I think

       

      It will sum up the values of the lastdate that meets the criteria

       

      I duplicated the date and it worked

       

      You can share you file if you like

        I have tried following DAX with the sample data in the attached Excel-file. Same error:
        "A date column containing duplicate dates was specified in the call to function 'LASTDATE'. This is not supported."

         

        TEST = 
VAR TheDate = DATE ( 2018 , 1 , 5 )
RETURN
    SUMMARIZE (
        Blad1,
        Blad1[order_id],
        "The_Qty", CALCULATE (
            SUM ( Blad1[qty] ),
            LASTDATE (
                FILTER (
                    VALUES ( Blad1[log_date] ),
                    Blad1[log_date] <= TheDate
                )
            )
        )
    )
