## Previous Year YTD, DAX help

Hi guys,

I am having problem with YTD for previous year.

I am using following formula so i can compare YTD till current date

```YTD LY =
'Date'[Date]<=LASTNONBLANK('Data'[Date],[Amount Sum])
),
-1,Year
)
)```

But problem i am having is that calculation starts only after first record in curret year. It follwing picture we can see that calcualtion starts from January 11th instead of January 1st. Is there a way to fix this?

```YTD LY V2_B =
VAR _Last =
CALCULATE ( LASTNONBLANK ( Data[Date]; [YTD] ); ALL ( 'Date'[Date] ) )
VAR _LastVal =
CALCULATE (
CALCULATE ( [YTD]; SAMEPERIODLASTYEAR ( 'Date'[Date] ) );
'Date'[Date] = _Last
)
RETURN
IF (
SELECTEDVALUE ( 'Date'[Date] ) <= _Last;
CALCULATE ( [YTD]; SAMEPERIODLASTYEAR ( 'Date'[Date] ) );
_LastVal
)```

`YTD Prev Year = CALCULATE( [YTD], SAMEPERIODLASTYEAR('Date'[Date]))`

Hi @morz3d

This might be a quick and dirty solution:

```YTD LY V2 =
VAR _Last =
CALCULATE ( LASTNONBLANK ( Data[Date]; [YTD] ); ALL ( 'Date'[Date] ) )
RETURN
IF (
SELECTEDVALUE ( 'Date'[Date] ) <= _Last;
CALCULATE ( [YTD]; SAMEPERIODLASTYEAR ( 'Date'[Date] ) )
)```

or this if you want to show the result only where [Amount PY] is non-blank

```YTD LY V3 =
VAR _Last =
CALCULATE ( LASTNONBLANK ( Data[Date]; [YTD] ); ALL ( 'Date'[Date] ) )
RETURN
IF (
SELECTEDVALUE ( 'Date'[Date] ) <= _Last
&& NOT ISBLANK ( [Amount PY] );
CALCULATE ( [YTD]; SAMEPERIODLASTYEAR ( 'Date'[Date] ) )
)```

Thanks @AlB

I fount this one lamost perfectly fitting my needs.

Is there maybe a way to fill other cell values with last YTD value (44 in thi case), like we have for normal YTD function.

So basically YTD PY would summ all PY values will last value of current day, and after that one it will just show lates value.

This woul add more data from PY to the YTD sum.

Considering this case i would like to remain on sum of 44 since this is all PY data available till January 13th
