Data Transformation
I have the following data:
| ID | Role | Manager Name |
| 1000 | admin | John |
| 1000 | viewer | Jackson |
| 1001 | admin | Ronnie |
| 1002 | admin | Lillie |
| 1003 | admin | Paul |
| 1003 | viewer | Jessica |
And I want to achieve this final result:
| ID | Role | Manager Name | Viewer Name |
| 1000 | admin | John | Jackson |
| 1001 | admin | Ronnie | |
| 1002 | admin | Lillie | |
| 1003 | admin | Paul | Jessica |
Kindly suggest the best approach to do this. Thanks.
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("i45WMjQwMFDSUUpMyc3MA9Je+Rl5SrE6cPGyzNTy1CKQRGJydnE+XM4QSU9Qfl5eZipMxghJxiczJwchY4wkE5BYmoMsjrAntbg4MzlRKTYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Role = _t, #"Manager Name" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Role", type text}, {"Manager Name", type text}}), #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([Role] = "admin")), Custom1 = Table.SelectRows(#"Changed Type", each ([Role] = "viewer")), #"Merged Queries" = Table.NestedJoin(#"Filtered Rows", {"ID"}, Custom1, {"ID"}, "Custom1", JoinKind.LeftOuter), #"Expanded Custom1" = Table.ExpandTableColumn(#"Merged Queries", "Custom1", {"Manager Name"}, {"Viewer Name"}) in #"Expanded Custom1"
