Need help in converting below tableau formula to power bi

[ShyamS]

Hello All,

It will be very helpful if anyone can help me out to convert this tableau formula to power bi measure.

SUM((FIXED DATEPART('quarter', [Calendar Day)), DATEPART('year', [Calendar Day]): SUM(IF DATEPART('quarter', [Calendar Day]) = DATEPART('quarter', [Current Day MY]-1) and DATEPART('year', [Calendar Day)) DATEPART('year', [Current Day MY]-1) THEN [WORKING DAY YTD] END))).

Thank you in advance for your quick response and valuable time.

Hi @ShyamS 

Thanks for the reply from @Greg_Deckler , please allow me to provide another insight:

Here's a DAX formula that should provide the equivalent functionality:

Measure =
VAR CurrentQuarter =
    QUARTER ( MAX ( 'Table'[Current Day MY] ) ) - 1
VAR CurrentYear =
    YEAR ( MAX ( 'Table'[Current Day MY] ) )
VAR PreviousQuarterEnd =
    IF (
        CurrentQuarter = 0,
        DATE ( CurrentYear - 1, 12, 31 ),
        EDATE ( DATE ( CurrentYear, CurrentQuarter * 3, 1 ), -1 )
    )
VAR PreviousQuarterStart =
    EDATE ( PreviousQuarterEnd, -2 )
RETURN
    CALCULATE (
        SUM ( 'Table'[WORKING DAY YTD] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Calendar Day] >= PreviousQuarterStart
                && 'Table'[Calendar Day] <= PreviousQuarterEnd
        )
    )

Please note, you might need to adjust the table and column names () to match your actual data model in Power BI.

If the above one can't help you, could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:
