[THENNA_41]

 I have the table name called Inventory  sheet . this table   sample data looks like below 

Version      Attribute      Value         Weekstartdate

pods         Demand         10            15  March  2021 

pods         DOI                20             14 November 2021 

pods         Demand         50            22 March 2021 

pods          DOI                40            21 November 2021 

pods         Demand         30            29 March 2021 

pods         Demand         50            05  April 2021 

pods         Demand         60            12  April 2021

pods         Demand         90            19 April 2021 

pods         Demand         10            26 April 2021 

I am trying to  get demand value from selected date to next three Months. i have  tired below measures

3 months total demand = CALCULATE([3 months total values],FILTER(Append1, Append1[Attributes]="Demand"))

3 months total values =

VAR LastDate_ = LASTDATE(Append1[Week Start date])

RETURN

    CALCULATE(

        SUM(Append1[Value]),

        DATESINPERIOD(Append1[Week Start date], LastDate_, 3, MONTH)

    )

But iam not getting correct value .  also attached  pbi  fILE ALSO

Hi @THENNA_41 ,

1.Please to create a successive date table by “Append” table, and create a model

Calendar =
CALENDAR (
    FIRSTDATE ( 'Append'[Weekstartdate] ),
    LASTDATE ( 'Append'[Weekstartdate] )
)

2.Create two measure

Measure =
VAR cur_date =
    SELECTEDVALUE ( 'Calendar'[Date] )
RETURN
    CALCULATE (
        SUM ( 'Append'[Value] ),
        DATESINPERIOD ( 'Calendar'[Date], cur_date, 3, MONTH )
    )

Measure2 =
VAR cur_ste =
    SELECTEDVALUE ( 'Append'[Attribute] )
RETURN
    IF (
        cur_ste = "Demand",
        CALCULATE ( [Measure], 'Append'[Attribute] = "Demand" )
    )

Add a table visual:

@amitchandak  sir  I have created Date table and also created new measure but values not getting correctly . please find the created measure below

Date = ADDCOLUMNS(CALENDAR(DATE(2020,1,1),DATE(2025,12,31)),"Dateasinteger",FORMAT([Date],"YYYYMMDD"),"YEAR",YEAR([Date]))

Rolling 3 = CALCULATE(sum(Append1[Value]),FILTER(Append1,Append1[Attributes]="Demand"),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),3,MONTH))

[amitchandak]

@THENNA_41 , Please use date table and try

example

Rolling 3 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),3,MONTH))

and why there is no demand filter in the second measure
