Dynamically create months-year in a table

Hi,ViralPatel212 I am glad to help you.
Hello,amitchandak ,thanks for your concern about this issue.

Your answer is excellent!
And I would like to share some additional solutions below.
Your original code is very good, I modified the Order column's sorting logic to achieve the order you need, sorting from closest to farthest in time.

DIM Date Filter_change = 
VAR _latest = MAX('DIM Calendar (Ranking)'[Date])
VAR _oldest = DATE(2023, 5, 22) -- Specific start date
VAR _previousYearStart = DATE(YEAR(_latest) - 1, 1, 1)
VAR _previousYearEnd = DATE(YEAR(_latest) - 1, 12, 31)
VAR _startOfPreviousMonth = EOMONTH(_latest, -2) + 1
VAR _endOfPreviousMonth = EOMONTH(_latest, -1)
VAR _endOfPreviousMonth2 = EOMONTH(_latest, -2)
VAR _startDate = DATE(YEAR(_oldest), MONTH(_oldest), 1)
RETURN
UNION(
    ADDCOLUMNS(
        CALENDAR(_startOfPreviousMonth, _endOfPreviousMonth),
        "Date Periods", "Most Recent Month",
        "Order", 1
    ),
    ADDCOLUMNS(
        CALENDAR(_startDate, _endOfPreviousMonth2),
        "Date Periods", FORMAT([Date], "MMM YY"),
        "Order", 
        SWITCH(
            TRUE(),
            FORMAT([Date], "MMM YY") = "May 24", 2,
            FORMAT([Date], "MMM YY") = "Apr 24", 3,
            FORMAT([Date], "MMM YY") = "Mar 24", 4,
            FORMAT([Date], "MMM YY") = "Feb 24", 5,
            FORMAT([Date], "MMM YY") = "Jan 24", 6,
            FORMAT([Date], "MMM YY") = "Dec 23", 7,
            FORMAT([Date], "MMM YY") = "Nov 23", 8,
            FORMAT([Date], "MMM YY") = "Oct 23", 9,
            FORMAT([Date], "MMM YY") = "Sep 23", 10,
            FORMAT([Date], "MMM YY") = "Aug 23", 11,
            FORMAT([Date], "MMM YY") = "Jul 23", 12,
            FORMAT([Date], "MMM YY") = "Jun 23", 13,
            FORMAT([Date], "MMM YY") = "May 23", 14,
            DATEDIFF(_startDate, EOMONTH([Date], 0), MONTH) + 15
        )
    ),
    ADDCOLUMNS(
        CALENDAR(DATE(YEAR(_latest), 1, 1), _latest),
        "Date Periods","YTD",
        "Order", DATEDIFF(_startDate, _latest, MONTH) + 16
    ),
    -- Dynamically generate quarters for the current year
    ADDCOLUMNS(
        FILTER(
            CALENDAR(DATE(YEAR(_latest), 1, 1), _latest),
            MONTH([Date]) <= MONTH(_latest)
        ),
        "Date Periods", "Q" & FORMAT([Date], "Q YYYY"),
        "Order", DATEDIFF(_startDate, _latest, MONTH) + 17 + QUARTER([Date]) - 1
    ),
    -- Dynamically generate quarters for the previous year
    ADDCOLUMNS(
        FILTER(
            CALENDAR(_previousYearStart, _previousYearEnd),
            MONTH([Date]) <= 12 &&
            YEAR([Date]) = YEAR(_previousYearStart)
        ),
        "Date Periods", "Q" & FORMAT([Date], "Q YYYY"),
        "Order", DATEDIFF(_startDate, _latest, MONTH) + 21 + QUARTER([Date]) - 1
    ),
    -- Additional hardcoded years or custom periods can be added here
    ADDCOLUMNS(
        CALENDAR(DATE(2023, 1, 1), DATE(2023, 12, 31)),
        "Date Periods", "2023",
        "Order", DATEDIFF(_startDate, _latest, MONTH) + 25
    ),
    -- Add custom periods if needed
    ADDCOLUMNS(
        CALENDAR(_oldest, _latest),
        "Date Periods", "Custom",
        "Order", DATEDIFF(_startDate, _latest, MONTH) + 26
    )
)

 Sort the fields in the table by [Order].

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
