How to create a Fiscal Week No

DAX DAX Calculations
1

Hi,

I created my date table using the example by SAM and I renamed it Date.

I need help in creating the Fiscal week. My financial year starts on 1 April

Below is the query I used:

= (StartDate as date, EndDate as date, FYStartMonth as number) as table =>
  let
    DayCount = Duration.Days(Duration.From(EndDate - StartDate)),
    Source = List.Dates(StartDate,DayCount,#duration(1,0,0,0)),
    TableFromList = Table.FromList(Source, Splitter.SplitByNothing()),   
    ChangedType = Table.TransformColumnTypes(TableFromList,{{"Column1", type date}}),
    RenamedColumns = Table.RenameColumns(ChangedType,{{"Column1", "Date"}}),
    InsertYear = Table.AddColumn(RenamedColumns, "Year", each Date.Year([Date]),type text),
    InsertYearNumber = Table.AddColumn(RenamedColumns, "YearNumber", each Date.Year([Date])),
    InsertQuarter = Table.AddColumn(InsertYear, "QuarterOfYear", each Date.QuarterOfYear([Date])),
    InsertMonth = Table.AddColumn(InsertQuarter, "MonthOfYear", each Date.Month([Date]), type text),
    InsertDay = Table.AddColumn(InsertMonth, "DayOfMonth", each Date.Day([Date])),
    InsertDayInt = Table.AddColumn(InsertDay, "DateInt", each [Year] * 10000 + [MonthOfYear] * 100 + [DayOfMonth]),
    InsertMonthName = Table.AddColumn(InsertDayInt, "MonthName", each Date.ToText([Date], "MMMM"), type text),
    InsertCalendarMonth = Table.AddColumn(InsertMonthName, "MonthInCalendar", each (try(Text.Range([MonthName],0,3)) otherwise [MonthName]) & " " & Number.ToText([Year])),
    InsertCalendarQtr = Table.AddColumn(InsertCalendarMonth, "QuarterInCalendar", each "Q" & Number.ToText([QuarterOfYear]) & " " & Number.ToText([Year])),
    InsertDayWeek = Table.AddColumn(InsertCalendarQtr, "DayInWeek", each Date.DayOfWeek([Date])),
    InsertDayName = Table.AddColumn(InsertDayWeek, "DayOfWeekName", each Date.ToText([Date], "dddd"), type text),
    InsertWeekEnding = Table.AddColumn(InsertDayName, "WeekEnding", each Date.EndOfWeek([Date]), type date),
    InsertWeekNumber= Table.AddColumn(InsertWeekEnding, "Week Number", each Date.WeekOfYear([Date])),
    InsertMonthnYear = Table.AddColumn(InsertWeekNumber,"MonthnYear", each [Year] * 10000 + [MonthOfYear] * 100),
    InsertQuarternYear = Table.AddColumn(InsertMonthnYear,"QuarternYear", each [Year] * 10000 + [QuarterOfYear] * 100),
    ChangedType1 = Table.TransformColumnTypes(InsertQuarternYear,{{"QuarternYear", Int64.Type},{"Week Number", Int64.Type},{"Year", type text},{"MonthnYear", Int64.Type}, {"DateInt", Int64.Type}, {"DayOfMonth", Int64.Type}, {"MonthOfYear", Int64.Type}, {"QuarterOfYear", Int64.Type}, {"MonthInCalendar", type text}, {"QuarterInCalendar", type text}, {"DayInWeek", Int64.Type}}),
    InsertShortYear = Table.AddColumn(ChangedType1, "ShortYear", each Text.End(Text.From([Year]), 2), type text),
    AddFY = Table.AddColumn(InsertShortYear, "FY", each "FY"&(if [MonthOfYear]>=FYStartMonth then Text.From(Number.From([ShortYear])+1) else [ShortYear]))
in
    AddFY

What is the logic for determining that fiscal week number in your specific case?

Hi,

Hope you are doing good…

You can get the same result by adding new column using DAX in the existing table.

//Creating Variable for Week and Month
FiscalWeek = 
VAR WeekStartsOn = "Mon"
VAR FiscalStartMonth = 4

VAR FiscalFirstDay = 
    IF(
        MONTH('Calendar'[Date]) < FiscalStartMonth,
        DATE(
            YEAR('Calendar'[Date])-1,
            FiscalStartMonth,
            1
        ),
        DATE(
            YEAR('Calendar'[Date]),
            FiscalStartMonth,
            1
        )
    )
VAR FilteredTableCount = 
    COUNTROWS(
        FILTER(
            SELECTCOLUMNS(
                GENERATESERIES(
                    FiscalFirstDay,
                    'Calendar'[Date]
                ),
                "Dates",
                [Value]
            ),
        FORMAT([Dates],"ddd") = WeekStartsOn
        )
    )
VAR WeekNos = 
    IF(
        FORMAT(FiscalFirstDay,"ddd") <> WeekStartsOn,
        FilteredTableCount + 1,
        FilteredTableCount
    )
RETURN

"Week " & WeekNos

Hi and thanks for this…but how do you sort the fiscal week number generated from this DAX?
