Dax measure for if date is smaller than maximum selected date from slicer then sumA else SumB

[ILLANA_N]

I want to show a matrix table showing actuals if dates is smaller than e.g. 31 May 2025 then budget values if after this date

I was using this formula

FORECAST = IF(FIRSTDATE(Budget_data[Date]) <= DATE(2025,05,31),sum('PnL Data_2025'[Amount]),sum(Budget_data[Amount]))

but I now want the dashboard user to select a dates on the slicer instead of me hard coding the cut off date.

Hi,

I am not sure how your semantic model looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

Expected result measure: = 
VAR _selecteddate =
    SELECTEDVALUE ( 'Calendar slicer'[date], DATE ( 2025, 5, 31 ) )
VAR _pnldata =
    SUM ( 'PnL Data_2025'[amount] )
VAR _budget =
    SUM ( Budget_data[amount] )
VAR _t =
    ADDCOLUMNS (
        VALUES ( 'Calendar'[date] ),
        "@result",
            IF (
                'Calendar'[date] <= _selecteddate,
                CALCULATE ( SUM ( 'PnL Data_2025'[amount] ) ),
                CALCULATE ( SUM ( Budget_data[amount] ) )
            )
    )
RETURN
    SUMX ( _t, [@result] )

@ILLANA_N Create a date slicer in your Power BI report.
Use the SELECTEDVALUE function to get the date selected by the user.

DAX
FORECAST =
VAR SelectedDate = SELECTEDVALUE(DateTable[Date])
RETURN
IF(
SelectedDate <= DATE(2025, 05, 31),
SUM('PnL Data_2025'[Amount]),
SUM(Budget_data[Amount])
)
