Previous Month Segment

Hi All, 

 

Im trying to get a value coming from the previous month on the same table, 

 

I tried the following, but always got blank results. 

PM Segment = CALCULATE (
FIRSTNONBLANK(Roster[Segments_], 1 ),
FILTER ( ALL ( Roster ), Roster[IDFDATE]= Roster[IDPMFDATE] )
)
my table has the following

IDFDate = ID and Current Month

IDPMFDATE = ID and Previous Month

 

any idea why its showing as blank?

Need Help

    Hi Lobs ,

     

    FILTER ( ALL ( Roster ), Roster[IDFDATE]= Roster[IDPMFDATE] )

    The problem may be in this filter condition.

     

    Please try this:

    Column = CALCULATE(FIRSTNONBLANK(Roster[Segments_],1),FILTER(Roster,EARLIER(Roster[IDFDATE])=Roster[IDFDATE]&&Roster[IDPMFDATE] IN VALUES(Roster[IDFDATE])))

    If segment is obtained by month, create two columns respectively to represent the current month and previous month, and the formula is similar to the above.

     

    Best Regards,
    Liang

    Lobs , not very clear, But you should use time intelligence with date table example

     

    MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
    last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
    last month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth('Date'[Date]))
