RETURN
    SUMMARIZE (
        Blad1,
        Blad1[order_id],
        "The_Qty", CALCULATE (
            SUM ( Blad1[qty] ),
            TOPN (
                1,
                FILTER ( VALUES ( Blad1[log_date] ), Blad1[log_date] <= TheDate ),

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
                )
            )
        )
    )

Example data here
