GROUP table to boolean

Hi all,

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

Order NrCustomerKey
555ABC-01A
555BDA-01B
556ABC-02A
557ABC-03A
558BDA-02C

 

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

Order NrABCBDAABC KeyBDA Key
555TRUETRUEFALSETRUE
556TRUEFALSEFALSEFALSE
557TRUEFALSEFALSEFALSE
558FALSETRUEFALSETRUE

 

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?

Need Help

    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"
