Need to fetch multiple values from the same table
Hello, I have a problem that I believe it's simple but I haven't been able to do this.
Imagine a table like this
| L1column | L2column | Number_ext |
| 1.1 Rice | ||
| 1.1 Rice | 1.1.1 Blue Rice | FIVE |
| 1.1 Rice | 1.1.2 Green Rice | |
| 1.2 Potatoes | ||
| 1.2 Potatoes | 1.2.1 Old Potatoes | TWELVE |
| 1.1 Rice | 1.1.1 Blue Rice | TEN, ELEVEN |
| 1.1 Rice | 1.1.1 Blue Rice |
I want to be able to create a new column that concatenates all the Number_ext column on the rows that have only the L1values and not L2values. Something like this:
| L1column | L2column | Number_ext | New column |
| 1.1 Rice | FIVE, TEN, ELEVEN | ||
| 1.1 Rice | 1.1.1 Blue Rice | FIVE | |
| 1.1 Rice | 1.1.2 Green Rice | ||
| 1.2 Potatoes | TWELVE | ||
| 1.2 Potatoes | 1.2.1 Old Potatoes | TWELVE | |
| 1.1 Rice | 1.1.1 Blue Rice | TEN, ELEVEN | |
| 1.1 Rice | 1.1.1 Blue Rice |
I've been trying Lookups and filters and new tables but I haven't been able to do this.
Can someone please help me with this?
Thank you!

Hello dsbuilder
check out this solution. It uses Table.Group and AddColumn. This will write your requested data in every column, no only in the first 🙂
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQzVAjKTE5V0lFSAONYHRRBIBPIccopTYWJuHmGuWJTZaTgXpSamocwDaLGSCEgvySxJD+1GM0KFAkgF2iaf04KsmBIuKsPdrtQXRTi6qej4OrjGubqR1gx0PpYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [L1column = _t, L2column = _t, Number_ext = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"L1column", type text}, {"L2column", type text}, {"Number_ext", type text}}), #"Grouped Rows" = Table.Group(#"Changed Type", {"L1column"}, {{"AllRows", each _, type table [L1column=text, L2column=text, Number_ext=text]}}), #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Conc", each Text.Combine([AllRows][#"Number_ext"])), #"Expanded AllRows" = Table.ExpandTableColumn(#"Added Custom", "AllRows", {"L1column", "Number_ext"}, {"L1column.1", "Number_ext"}) in #"Expanded AllRows"Copy paste this code to the advanced editor in a new blank query to see how the solution works.
