Changing duplicates into Null

[jinweitan]

Hi all,

I would like to change duplicates in my row into null

For example this as my original table, where I would like to change the orange boxes into null as they are replication.

Becoming into this:

and Ideally my end product is do calculate the Score based on the Type.

Hope someone can give some guidance.

Many thanks.

@jinweitan ,

This is a Power Query Solution:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXIEYkMDpVgdnFwwxwjKMcLBc0Log3GVYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [GUID = _t, TYPE = _t, SCORE = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"GUID", Int64.Type}, {"TYPE", type text}, {"SCORE", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"GUID", "TYPE", "SCORE"}, {{"Rows", each Table.AddColumn(Table.AddIndexColumn(_, "Index", 1,1), "Score_2", each if [Index] > 1 then null else [SCORE]), type table }}),
    #"Removed Other Columns" = Table.SelectColumns(#"Grouped Rows",{"Rows"}),
    #"Expanded Rows" = Table.ExpandTableColumn(#"Removed Other Columns", "Rows", {"GUID", "TYPE", "Index", "Score_2"}, {"GUID", "TYPE", "Index", "Score_2"}),
    #"Renamed Columns" = Table.RenameColumns(#"Expanded Rows",{{"Score_2", "SCORE"}}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns",{{"GUID", Int64.Type}, {"TYPE", type text}, {"Index", Int64.Type}, {"SCORE", Int64.Type}})
in
    #"Changed Type1"

@jinweitan , better try a measure like

Measure = AVERAGEX(SUMMARIZE (filter('Table 1',not(isblank('Table 1'[Score]))),'Table 1'[GUID],'Table 1'[Type],'Table 1'[Score]),[score])
