Create Heirarchy in Power Query (not bi) Using Columns in Query that pulls from multiple tables

[Anonymous]

The current query I have is made up of merging multiple tables with some column calculations as well.

Everything works perfectly but their is no structure to the heirarchy.

For example, I have [Year] [Quarter] [Month]

When I put these into a pivot table as columns and only show columns with data, it works fine.

However, if I want each [Month] to show, even if the data is empty, it shows Jan through Dec four times under [Quater], making 48 columns.

How can I create a heirachy so that only certain month sow under certain quarters, and then weeks under months, etc. ?

Hi @Anonymous , 

I think you could create data structure like below, then use this in Matrix

let
    Source = List.Dates(#date(2020,1,1),365,#duration(1,0,0,0)),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Added Custom" = Table.AddColumn(#"Converted to Table", "querter", each Date.QuarterOfYear([Column1])),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "month", each Date.Month([Column1])),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "week", each Date.WeekOfMonth([Column1]))
in
    #"Added Custom2"

Column = ROUND( RAND()*10,0)
