Data Transformation

I have the following data:

IDRoleManager Name
1000adminJohn
1000viewerJackson
1001adminRonnie
1002adminLillie
1003adminPaul
1003viewer

Jessica

 

And I want to achieve this final result:

IDRoleManager NameViewer Name
1000adminJohnJackson
1001adminRonnie 
1002adminLillie 
1003adminPaulJessica

 

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"

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!
