Previous month measure figure is not correct

[Anonymous]

Hi,

I am trying get previous month figures, but it the DAX i have does not show the correct figure.

I have 3 measures:

Measure1 (correct):

-----------

Total List Price = CALCULATE(SUM(Purchases[Line Amount]), FILTER(Purchases, Purchases[General Product Posting Group] IN {"PART", "PART-SC"} && Purchases[Part Number] <> ""))

Measure2 (correct):

-----------

Testing WA Price Monthly =

VAR AnnualListPrice =CALCULATE([Total List Price], ALL('Posting Date'[FY Month Name Short], 'Posting Date'[FY Month]))

VAR MonthlyTable =

ADDCOLUMNS(

SUMMARIZE(

Purchases,

'Posting Date'[FY], 'Posting Date'[FY Month Name Short]

),

"MonthlyPrice", [Total List Price],

"WT", DIVIDE([Total List Price], AnnualListPrice)

)

Return

SUMX(

MonthlyTable,

[Wt]* [MonthlyPrice]

)

Measure3 (incorrect):

This measure shows the value of measure [Total List Price] instead [Testing WA Price Monthly]

-----------

Testing WA Price Monthly Prev =

CALCULATE([Testing WA Price Monthly]

, dateadd( 'Posting Date'[Date], -1,MONTH))

Hi @Anonymous 

Please try this Measure.

Testing WA Price Monthly Prev =

VAR max_date =

    MAX ( 'Posting date'[Date] )

VAR max_month =

    MONTH ( max_date )

VAR max_year =

    YEAR ( max_date )

VAR year =

    IF ( max_month = 1, max_year - 1, max_year )

VAR month =

    IF ( max_month = 1, 12, max_month - 1 )

VAR res =

    CALCULATE (

        [Testing WA Price Monthly],

        FILTER (

            ALL ( 'Posting date' ),

            YEAR ( 'Posting date'[Date] ) = year

                && MONTH ( 'Posting date'[Date] ) = month

        )

    )

RETURN

    res

The result looks like this:

@Anonymous , Try with date table , marked as date table , and use month from date table in visual

Testing WA Price Monthly Prev =
CALCULATE([Testing WA Price Monthly]
, dateadd( 'Date'[Date], -1,MONTH))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.

I just check the tabular model, 'Posting Date' is marked as date table.

Thanks @amitchandak , the table 'Posting Date' I am using is a date table and I am using the month form 'Posting Date' table. I am not sure what do you mean by "marked as a date table".

My data source is tabular model.
