DAX changing its value

[MAli_Ch]

Hi, I'm working on a report where I have to show quarterly data based upon one or multiple years selected from the filter. I want to store the smallest year value for which i have created a measure shared below. Lets say I select year 2024,2025 and 2026 from filter. Now I should get cumulative sum of each quarter with its previous year. If I hardcode year in my dax then it works fine otherwise it cumulate sum for each years individually which I dont want. below are the measures and screenshot of line chart with hardcode value and with measure's value.

(Measure to get smallest year)

MinYearSelected =

VAR SelectedYears =

    VALUES('DIM_DATE'[REPORT_YEAR])

RETURN

    MINX(SelectedYears, 'DIM_DATE'[REPORT_YEAR])

(Main Measure)

Cumulative Measure Sum =

var min_year = [MinYearSelected]

RETURN

CALCULATE(

    [udp high total fcst],

    FILTER(

        ALLSELECTED('DIM_DATE'[WEEK_END_DATE]),

        AND(

            ISONORAFTER('DIM_DATE'[WEEK_END_DATE], MAX('DIM_DATE'[WEEK_END_DATE]), DESC),

            YEAR('DIM_DATE'[WEEK_END_DATE]) >= min_year

        )

    ))

(Result I want using variable having smallest year value)
(Result I am getting using variable having smallest year value)

Hi @MAli_Ch 

please try

MinYearSelected =
MINX ( ALLSELECTED ( 'DIM_DATE'[REPORT_YEAR] ), 'DIM_DATE'[REPORT_YEAR] )

Hi @tamerj1, hope you are doing well. Thanks, your solution worked perfectly.
Just for my understanding can you explain what is the difference between my and your MinYearSelected measure. It seems to be almost same.

ALLSELECTED ignores the filter context of the visual and considers only the outer filter context represented by slicers and page filters etc.

Alright I get it, thanks again
