Calculate difference between current and previous row with a condition

I have a table and need to calculate a difference between 2 rows with a condition that it only applies to Agregation Type = All Branches - YTD and it is a diff between fiscal month and fiscal month-1.

 In the table I added a column Diff that should show those results. # of rows will grow and is added on a weekly basis.

Hi @Sultanista ,

 

You can try this method:

New column:

 

Diff =
VAR _curr =
    CALCULATE (
        SUM ( 'Table'[Applicants] ),
        'Table'[Agregation Type] = "All Branches - YTD"
    )
RETURN
    IF (
        [Fiscal Month] = 1
            || 'Table'[Agregation Type] <> "All Branches - YTD"
            || ISBLANK ( 'Table'[Applicants] ),
        BLANK (),
        _curr
            - CALCULATE (
                SUM ( 'Table'[Applicants] ),
                FILTER (
                    'Table',
                    [Agregation Type] = "All Branches - YTD"
                        && [Fiscal Year] = EARLIER ( 'Table'[Fiscal Year] )
                        && [Fiscal Month]
                            = EARLIER ( 'Table'[Fiscal Month] ) - 1
                )
            )
    )

 

The result is:

It works great! Is it possible to move those results from current place to the corresponding fiscal year and month but aggregation type = All Branches - MTD ? 

And having the 1st value of the year (month =1) same as in YTD?

Diff CC =
VAR _previous =
    MAXX (
        FILTER (
            Data,
            Data[Fiscal Year] = EARLIER ( Data[Fiscal Year] )
                && Data[Fiscal Month]
                    = EARLIER ( Data[Fiscal Month] ) - 1
                && Data[Agregation Type] = "All Branches - YTD"
        ),
        Data[Applicants]
    )
RETURN
    IF (
        Data[Agregation Type] = "All Branches - YTD"
            && NOT ISBLANK ( Data[Applicants] ) && NOT ISBLANK ( _previous ),
        Data[Applicants] - _previous
    )
