replace Duplicate values for each source in the one query

Hi Anonymous ,

Perhaps you can try:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtA1NFfSUTLKS1HwT0vLTE4tUorVQZbxKtJTMMYpa1yES8apKDMlPVUhJDUxF0nGEijjm1hcgqIcJOickZmahsUoS5yOs8RpPX4ZrA4zMsDiMLAgDoeB5bA6jIAMVoeBZVAcFgsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Source", type text}, {"Value", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Source"}, {{"Data", each _, type table [Source=nullable text, Value=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each Table.Distinct([Data])),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Value"}, {"Value"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"Data"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"Value", type text}})
in
    #"Changed Type1"
