Last 6 months data

Hello mb0307 

here a code that creates two variables (CreateTextForQueryEnd  and CreateTextForQueryStart) that you can use in your code

let
    Today = Date.From(DateTime.FixedLocalNow()),
    YearToday = Text.From(Date.Year(Today)),
    MonthToday = "0"&Text.From(Date.Month(Today)),
    DayToday = "0"&Text.From(Date.Day(Today)),
    CreateTextForQueryEnd = "[0DSDEL_DATE].["&YearToday&Text.End(MonthToday,2)&Text.End(DayToday,2)&"]",
    Minus6MonthsFirstDayOfMonth = Date.StartOfMonth(Date.AddMonths(Date.From(DateTime.FixedLocalNow()),-6)),
    Year6Months = Text.From(Date.Year(Minus6MonthsFirstDayOfMonth)),
    Month6Months = "0"&Text.From(Date.Month(Minus6MonthsFirstDayOfMonth)),
    Day6Months = "0"&Text.From(Date.Day(Minus6MonthsFirstDayOfMonth)),
    CreateTextForQueryStart = "[0DSDEL_DATE].["&Year6Months&Text.End(Month6Months,2)&Text.End(Day6Months,2)&"]"
in
    CreateTextForQueryStart

 Copy paste this code to the advanced editor in a new blank query to see how the solution works.
