Custom Quarter Column

[Brite]

Hello,

I am trying to create a custom column with the below requirements:

1) If the Month has more than 30 days, then the quarter should be the same until the next Sunday date

2) Else return the next quarter 

This is an example of what I have now

I am looking for:

(March 2022 had 31 days and the next Sunday was 04/03 therefore any day up until the next Sunday (04/03) should be Quarter 1)

W/E Company First Processed   Quarter Num                                 Quarter Num.1

2/6/2022	1	Q1-2022
2/13/2022	1	Q1-2022
2/20/2022	1	Q1-2022

Hi, @Brite ;

You add custom in powerbi query.

[date]-#duration(1,0,0,0)

= Table.AddColumn(#"Added Custom", "Start of Week", each Date.StartOfWeek([Custom])+#duration(1,0,0,0))

= Table.AddColumn(#"Inserted Start of Week", "Quarter1", each Date.QuarterOfYear([Start of Week]), Int64.Type)

= Table.RemoveColumns(#"Inserted Quarter",{"Custom", "Start of Week"})

M lanuage:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fc1BCoAwDETRq0jWlTSTaL1G16X3v0atiCAkXWQRHsxvjcAnIwMbJZL7quzzpZ6miT7oGvLCSmT69lyKc7rI6SJnHE4ayzc5r+JnJTZYZAdLTJdLfQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"W/E Company" = _t, num = _t, Quarter = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"W/E Company", type date}, {"num", Int64.Type}, {"Quarter", type text}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"W/E Company", "date"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns", "Custom", each [date]-#duration(1,0,0,0)),
    #"Inserted Start of Week" = Table.AddColumn(#"Added Custom", "Start of Week", each Date.StartOfWeek([Custom])+#duration(1,0,0,0)),
    #"Inserted Quarter" = Table.AddColumn(#"Inserted Start of Week", "Quarter1", each Date.QuarterOfYear([Start of Week]), Int64.Type),
    #"Removed Columns1" = Table.RemoveColumns(#"Inserted Quarter",{"Custom", "Start of Week"})
in
    #"Removed Columns1"

The final show:
