Calculate difference between versions of Forecast data

Hello,   I need help for a DAX measure to calculate Forecast Qty difference between versions for each Fiscal Qtr. A Fiscal Qtr may have multiple versions of Forecast. See example data below.   ...

    and try this 

    Measure = 
VAR NumQuarter = SELECTEDVALUE('Sales Forecast'[NumQuarter])-1
VAR PQTY = 
CALCULATE([FCST_QTY], 'Sales Forecast'[NumQuarter]= NumQuarter , REMOVEFILTERS('DimVersionNo'),REMOVEFILTERS(DimFYFISCAL))
RETURN
 [FCST_QTY] - PQTY

Hi mbudiman,

 

You can achieve it by first clculating previous version forecast

 

PrevVersionForecast =
VAR CurrentFiscal = MAX('Forecast'[Fiscal Qtr])
VAR CurrentVersionNo = MAX('Forecast'[Version No])
RETURN
CALCULATE(
MAX('Forecast'[Forecast Qty]),
FILTER(
ALL('Forecast'),
'Forecast'[Fiscal Qtr] = CurrentFiscal &&
'Forecast'[Version No] = CurrentVersionNo + 1
)
)

Then calculating the difference between them

 

ForecastDifference =
VAR CurrentForecast = MAX('Forecast'[Forecast Qty])
VAR PreviousForecast = [PrevVersionForecast]
RETURN
IF(
NOT ISBLANK(PreviousForecast),
CurrentForecast - PreviousForecast,
BLANK()
)
