Calculate date filter

Hello, 

 

I ve been trying to improve my calculation with additional date filter, but it doesnt make any diff. It behaves like it calculates the result for all dates

lukaszEltwin1_0-1671910890079.png

 

Everything is calculates in one table. measure reacts correctly to date slicer or filter visual modification, but only not for dax...

 

Aby idea what can be wrong?

Please try

Yield Mech. assemblyprevmonth =
VAR CurrentYearMonth =
    MAX ( 'Date'[Year Month Number] )
VAR MechAssembly =
    CALCULATETABLE (
        TJob,
        TJob[SekundærNavn] = "Mech. assembly",
        'Date'[Year Month Number] = CurrentYearMonth - 1,
        ALL ( 'Date' )
    )
RETURN
    ROUND (
        DIVIDE (
            SUMX ( MechAssembly, TJob[FirstPassQty] ),
            SUMX ( MechAssembly, TJob[Antal] )
        ),
        4
    )

Hi @Anonymous ,

 

Please try this measure:

 

(Try PARALLELPERIOD(TJob[Dato],-1,MONTH) instead of PREVIOUSMONTH(TJob[Dato]))

 

PrevMonth = 
CALCULATE(SUMX(Sales, Sales[Unit Cost]), PARALLELPERIOD('Date'[Date],-1,MONTH))

 

 

Then the result is as follows.

@v-tangjie-msft  Calculated you presented isnt filtering any date. Its result of sumx with function all to each month? Could you try to download contoso file. Maybe my settings for file are disrupting the calculation... I m running out of ideas

Hi @Anonymous 

bring CALCULATE at line number 2 instead of 5

Could you elaborate more? You mean putting sumx as VAR?

 

Yield Mech. assembly =
VAR nom =
    CALCULATE( SUMX(TJob, TJob[Antal]), TJob[SekundærNavn] = "Mech. assembly" , PREVIOUSMONTH(TJob[Dato]))
VAR den =
    CALCULATE(SUMX(TJob, TJob[FirstPassQty]), TJob[SekundærNavn] = "Mech. assembly", PREVIOUSMONTH(TJob[Dato]))
RETURN
    ROUND(
        DIVIDE (
            den,
             nom),
            4)

Please try

Yield Mech. assembly111 =
CALCULATE (
VAR MechAssembly =
FILTER ( TJob, TJob[SekundarNavn] = "Mech. assembly" )
RETURN
ROUND (
DIVIDE (
SUMX ( MechAssembly, TJob[Antal] ),
SUMX ( MechAssembly, TJob[FirstPassQty] )
),
4
),
PREVIOUSMONTH ( TJob[Dato] )
)

Idk know why but the measure keeps displaying blank after previous month function. So as few others i had try for example

 

Date column is correctly formatted as date, rest as whole number.

@Anonymous 
Does this work for you?

Could you reference measure to VAR version. Contoso model looks very good, refering to year month number is pretty nifty idea, but when i tried to copy results....

It still wont give me the previous month

@Anonymous 
Can you copy/paste this code so I can modify?

            SUMX ( MechAssembly, TJob[Antal] ) ),
            4),
            ALL('Date'),
            'Date'[Year Month Number] = MAX('Date'[Year Month Number]) -1)

You re a God!

 

The magic question what is the purpose of previousmonth function if its not working... or why is it not working

@Anonymous 
It should work but I usually don't like to use time intellagence functions. You may try

Yield Mech. assemblyprevmonth =
VAR CurrentYearMonth =
    MAX ( 'Date'[Year Month Number] )
VAR MechAssembly =
    CALCULATETABLE (
        TJob,
        TJob[SekundærNavn] = "Mech. assembly",
        PREVIOUSMONTH ( 'Date'[Date] )
    )
RETURN
    ROUND (
        DIVIDE (
            SUMX ( MechAssembly, TJob[FirstPassQty] ),
            SUMX ( MechAssembly, TJob[Antal] )
        ),
        4
    )

Forgot to mention that it returns blank if the date table is not filtered i.e. at the grand total level.

And it returns blank. Well it doesnt matter right now. Thank you.

 

To bad dax guides for time intelligence are showing easy results, nothing real life databases. At least for me
