Copy lastnonblank value for future date

[Marwen89]

Hi, 

I want to copy lastnonblank value for future date. 

For exemple:

Lastnonblank value 100 at 22 February 2022,

I want to copy it for all periode >this date. 

How to do this with Dax? 

Any suggestions please?

Thanks

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.

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]))
