Hi Bhatt23 

Based on your description, if there are no calculation group, will they shold be sum together? such as the BN101.

I create the following sample based on the understanding I have described, you can refer it.

Sample data is the same as you provided.

Create the following measures.

Calculation_group =
MAXX (
    FILTER (
        ALLSELECTED ( 'Formula with mapping' ),
        [Division]
            IN VALUES ( 'Data'[Division] )
                && [Subdivision] IN VALUES ( 'Data'[Subdivision] )
    ),
    [Calculation based on DPID which represent Subdivision]
)

Left_calculation = LEFT([Calculation_group],SEARCH(")",[Calculation_group],,BLANK()))

Right_calculation = RIGHT([Calculation_group],LEN([Calculation_group])-SEARCH(")",[Calculation_group],,BLANK()))

Sum_calculation =
VAR a =
    SUMX (
        FILTER (
            ALLSELECTED ( 'Data' ),
            [Division]
                IN VALUES ( 'Data'[Division] )
                    && [Subdivision]
                        IN VALUES ( 'Data'[Subdivision] ) && CONTAINSSTRING ( [Left_calculation], [DPID] )
        ),
        [VALUE]
    )
VAR b =
    SUMX (
        FILTER (
            ALLSELECTED ( 'Data' ),
            [Division]
                IN VALUES ( 'Data'[Division] )
                    && [Subdivision]
                        IN VALUES ( 'Data'[Subdivision] ) && CONTAINSSTRING ( [Right_calculation], [DPID] )
        ),
        [VALUE]
    )
RETURN
    SWITCH (
        TRUE (),
        [Calculation_group] = BLANK (),
            SUMX (
                FILTER (
                    ALLSELECTED ( 'Data' ),
                    [Division]
                        IN VALUES ( 'Data'[Division] )
                            && [Subdivision] IN VALUES ( 'Data'[Subdivision] )
                ),
                [VALUE]
            ),
        [Left_calculation] = BLANK (), b,
        [Left_calculation] <> BLANK (), a - b
    )

Output

Best Regards!
