Previous Month Calculation getting Wrong

[Srikantht]

Hi All,

I am trying to get previous month values by using the below dax but getting wrong values. Can any one help in this to get the expected output. Thanks in Advance. 

Dax : 

Previous Month = CALCULATE(SUM(value),
ALL(Table),
PREVIOUSMONTH(Table[Date]))

Hi @Srikantht ,

Please try create a measure with below dax formula, but you need adjust it according to your actua calculate context:

Previous month =
VAR cur_date =
    SELECTEDVALUE ( 'Table'[Date] )
VAR _result =
    CALCULATE (
        MAX ( [Current Month] ),
        FILTER ( ALL ( 'Table' ), DATEDIFF ( cur_date, [Date], MONTH ) = -1 )
    )
RETURN
    _result

Please refer the attached .pbix file.
