Answer 1

您可以使用電源查詢來實現此目的

 let
        Source = Excel.Workbook(File.Contents("C:\Ashok\Power BI\Stack Overflow\data_08_nov_21.xlsx"), null, true),
        Data_Sheet = Source{[Item="Data",Kind="Sheet"]}[Data],
        #"Promoted Headers" = Table.PromoteHeaders(Data_Sheet, [PromoteAllScalars=true]),
        #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"MonthEndDate ", type date}, {" date ", type date}}),
        #"Inserted Day" = Table.AddColumn(#"Changed Type", "Day", each Date.Day([#" date "]), Int64.Type),
        #"Added Custom" = Table.AddColumn(#"Inserted Day", "Custom", each if[Day] < 15 
    
    then Date.EndOfMonth( Date.AddMonths([#" date "], -1))
    else Date.EndOfMonth([#" date "])),
        #"Renamed Columns" = Table.RenameColumns(#"Added Custom",{{"Custom", "ResultDate"}})
    in
        #"Renamed Columns"
