Dynamic measures( Sum and Difference) for based on Slicer selection

Hi kkalyanrr ,

Please try this measure after adding a new table for slicer:

Measure =
VAR _all =
    ALLSELECTED ( forSlicer[Type] )
VAR countSele =
    COUNTROWS ( FILTER ( 'forSlicer', 'forSlicer'[Type] IN _all ) )
VAR _income =
    CALCULATE (
        SUM ( 'Table'[Amount] ),
        FILTER ( 'Table', 'Table'[CategoryName] = "Income" )
    )
VAR _sum =
    CALCULATE (
        SUM ( 'Table'[Amount] ),
        FILTER ( 'Table', 'Table'[CategoryName] IN _all )
    )
RETURN
    IF (
        countSele = 1
            && "Income" IN _all,
        _income,
        IF ( countSele >= 2 && "Income" IN _all, _income * 2 - _sum, _sum )
    )

My final output looks like this : ( measure in the lower left corner is  just for test)

Here is the pbix file.
