Power Query /M version of CALENDARAUTO() DAX function?

igaca

According to the BOL, CALENDARAUTO returns a table with a single column named “Date” that contains a contiguous set of dates. The range of dates is calculated automatically based on data in the model. Based on my test, in the model means it would detect the date low and high year boundaries in all tables. Though I'm not familar with Power query, I'd doubt there's an equivalent in Power query.

For copy and paste purpose, you can use a DAX formula as well. Check

DimDate =
VAR fiscal_year_end_month = 3
RETURN
    ADDCOLUMNS (
        CALENDARAUTO ( fiscal_year_end_month ),
        "DateAsInteger", FORMAT ( [Date], "YYYYMMDD" ),
        "Year", YEAR ( [Date] ),
        "Fiscal Year", IF (
            MONTH ( [DATE] ) <= fiscal_year_end_month,
            YEAR ( [DATE] ) - 1,
            YEAR ( [DATE] )
        ),
        "Quarter", "Q" & FORMAT ( [Date], "Q" ),
        "Fiscal Quarter", "Q"
            & FORMAT (
                IF (
                    fiscal_year_end_month < MONTH ( [Date] ),
                    DATE ( YEAR ( [Date] ), MONTH ( [Date] ) - fiscal_year_end_month, 1 ),
                    DATE ( YEAR ( [Date] ) - 1, MONTH ( [Date] ) + 12 - fiscal_year_end_month, 1 )

Change the 3 to your real fiscal end month accordingly.
