    Hi Marwen89 ,

     

    Power BI doesn't support you to transform the existing column by Dax. You need to create a new column by Dax to achieve your goal.

    Try this code to create calculated columns.

    Fill Down CANADA = 
VAR _Last = CALCULATE(LASTNONBLANKVALUE('Table'[Date], SUM('Table'[CANADA])), ALLSELECTED())
return
IF('Table'[CANADA] = BLANK(),_last,'Table'[CANADA])
    Fill Down EUROPE = 
VAR _Last = CALCULATE(LASTNONBLANKVALUE('Table'[Date], SUM('Table'[EUROPE])), ALLSELECTED())
return
IF('Table'[CANADA] = BLANK(),_last,'Table'[EUROPE])

    Result is as below.

    Marwen89 , Try a measure like

    var _last = calculate(lastnonblankvalue(Date[Date], Sum(Table[Value])), allselected())
    return
    if(max(Date[Date]) >= maxx(allselected(date), date[date]), _last, Sum(Table[Value]))

      Hi Marwen89 ,

       

      Firstly, make sure there are future dates in your data model. We need actual data to calculate or do some transform in Power BI.

      If your table looks like as below. Sort your [Date] column by ascending. Then try Fill Down  function.

      Result is as below.
