    Hi, Anonymous 

     

    Based on the data you provide, you can try the following methods.

    Current value = SUM(Data[Value])
    Previous value = 
Var PrevDate=MAXX(FILTER(ALL('Data'[Date],Data[Year]),'Data'[Date]<SELECTEDVALUE('Data'[Date])&&[Year]=SELECTEDVALUE(Data[Year])),'Data'[Date])
Var Prevalue=CALCULATE([Current value],FILTER(ALL(Data),[Date]=PrevDate))
Return
Prevalue
    Outcome = IF([Previous value]<>BLANK(), [Current value]-[Previous value])

    The result of the calculation is different from the result you expect. Consider if there is a problem with your desired result calculation?

     

    Let me give you an example.

    But in your results.

    Please check if there is a problem with your result calculation in Excel, thank you.
