Use Power Query to show the high value of a list of a columns grouped

[Rigolleto]

Hi,

Could someone help me with some advise with this, as you can see in the screenshot, left side, I have 3 columns, STYLE, COLOR and TOTAL UNITS SOLD, basically what I need is the way to get an output like the fig 2 show, notice that for Style A  has 3 colors, I need to get from A only the high values, the same for STYLE B.

I did try grouping but when I use a MAX for COLOR Column then instand of show =  A C1 200 then I am getting A C3 200, see that the COLOR is geeting the highest , because the max()

Fig 1                                                            Fig 2

Hi @Rigolleto ,

How about this?

Before:

After:

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZY67DYAwDER3cZ3CHyJqzBiR91+DJChgjuak96TzuTU6qNApPZSZoiQhKGpi7bGh+DR03nzZcMOwcYvJ/nxVQayGw1e+NncGISg08dg0BiF/QREX", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Style = _t, Color = _t, #"Total Units Sold" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Style", type text}, {"Color", type text}, {"Total Units Sold", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Style", "Color"}, {{"Total Units Sold", each List.Max([Total Units Sold]), type nullable number}})
in
    #"Grouped Rows"

Let me know, if this solves your query 🙂
