GROUP table to boolean

[joshua1990]

Hi all,

I have a table that shows for each order the customer type and a specific key:

Order Nr	Customer	Key
555	ABC-01	A
555	BDA-01	B
556	ABC-02	A
557	ABC-03	A
558	BDA-02	C

Now I would like to group that table into this structure:

Order Nr	ABC	BDA	ABC Key	BDA Key
555	TRUE	TRUE	FALSE	TRUE
556	TRUE	FALSE	FALSE	FALSE
557	TRUE	FALSE	FALSE	FALSE
558	FALSE	TRUE	FALSE	TRUE

First I need two columns: [ABC] and [BDA] as a TRUE/FALSE if in column "Customer" the text begins with ABC or BDA.

Then I need again two columns: [ABC Key] and [BDA Key] if per Order and per Customer we can find a recods with Key "B" or "C".

How is this possible in Power Query?

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjU1VdJRcnRy1jUwBDGUYnVggk4ujhBBJ6igGUylEZJKc5igMZKgBUw7SKWzUmwsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Order Nr" = _t, Customer = _t, Key = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Order Nr", Int64.Type}, {"Customer", type text}, {"Key", type text}}),
    CustomerList = List.Buffer(List.Zip({#"Changed Type"[Order Nr],List.Transform(#"Changed Type"[Customer],each Text.Start(_,3))})),
    KeyList = List.Buffer(List.Zip({#"Changed Type"[Order Nr],List.Transform(#"Changed Type"[Customer],each Text.Start(_,3)), #"Changed Type"[Key]})),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"Customer", "Key"}),
    #"Removed Duplicates" = Table.Distinct(#"Removed Columns"),
    #"Added Custom" = Table.AddColumn(#"Removed Duplicates", "ABC", each List.Contains(CustomerList,{[Order Nr]}&{"ABC"})),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "BDA", each List.Contains(CustomerList,{[Order Nr]}&{"BDA"})),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "ABC Key#(tab)", each List.ContainsAny(KeyList,{{[Order Nr]}&{"ABC"}&{"B"},{[Order Nr]}&{"ABC"}&{"C"}})),
    #"Added Custom3" = Table.AddColumn(#"Added Custom2", "BDA Key", each List.ContainsAny(KeyList,{{[Order Nr]}&{"BDA"}&{"B"},{[Order Nr]}&{"BDA"}&{"C"}}))
in
    #"Added Custom3"
