Dynamic calculation based on Slicer value.

Prudhviraj,

Currently, we cannot achieve this requirement in table. To work around this, we could achieve the similar requirement in table visual.

create a table and some columns.

Table =
FILTER (
    CALENDAR ( DATE ( 2017, 1, 1 ), DATE ( 2017, 12, 31 ) ),
    DAY ( [Date] ) = 1
)

MonthName =
FORMAT ( 'Table'[Date], "MMMM" )

MonthNumber =
MONTH ( 'Table'[Date] )

Create two measure in your original table.

Filter =
VAR selectmonth =
    IF (
        HASONEFILTER ( 'Table'[MonthName] ),
        MAX ( 'Table'[MonthNumber] ),
        BLANK ()
    )
VAR Previous_month = selectmonth - 1
VAR check =
    IF (
        MAX ( Table1[MonthNumber] ) = selectmonth
            || MAX ( Table1[MonthNumber] ) = Previous_month,
        1,
        0
    )
RETURN
    check

Change =
VAR selectmonth =
    IF (
        HASONEFILTER ( 'Table'[MonthName] ),
        MAX ( 'Table'[MonthNumber] ),
        BLANK ()
    )
VAR Previous_month = selectmonth - 1
VAR currenttype =
    MAX ( Table1[Type] )
VAR currentregion =
    MAX ( Table1[Region] )
VAR currentmonth =
    MAX ( Table1[MonthNumber] )
RETURN
    IF (
        MAX ( 'Table1'[MonthNumber] ) = Previous_month,
        BLANK (),
        IF (
            MAX ( Table1[Amount] )
                - LOOKUPVALUE (
                    Table1[Amount],
                    Table1[Type], currenttype,
                    Table1[Region], currentregion,
                    Table1[MonthNumber], Previous_month
                )
                > 0,
            "increase",
            "decrease"
        )
    )

User Filter measure in you visual filter.
