Master Data potential duplicate analysis

I have a table "Vendor_TAX" where there is below list : 

 

Supplier IDTAX1TAX2TAX3
1A  
2 A 
3  A
4B  
5B  
6 B 
7  C
8  D
9 E 
10 C 

 

I need to identify the potential duplicate crossing all taxes - for each line, it should chetk : 

- If the TAX1 = TAX1 or TAX 2 or TAX3 for another supplier

- If the TAX2 = TAX1 or TAX 2 or TAX3 for another supplier

- If the TAX3 = TAX1 or TAX 2 or TAX3 for another supplier

 

Output would like like : 

Supplier IDTAX1TAX2TAX3Duplicate GroupDuplicate List
1A  11,2,3
2 A 11,2,3
3  A11,2,3
4B  24,5,6
5B  24,5,6
6 B 24,5,6
7  C37,1
8  D  
9 E   
10 C 37,1

It would group all the supplier that match the same taxes as well as listing them. 

 

I can't do this into Power Querry or in the table because I need to formula to follow the fitler input by the end user. 

 

Any idea how to acheive this ?

    Hi Martin0011 ,

    Please try like:

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXIEYhCK1YlWMoKwHWF8Y6gcSAjENwGynJDUm6LxzSBsJxjfHK7fGcy3gPNdwHxLCMcVpt7QAKYaJBALAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Supplier ID" = _t, TAX1 = _t, TAX2 = _t, TAX3 = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Supplier ID", Int64.Type}, {"TAX1", type text}, {"TAX2", type text}, {"TAX3", type text}}),
        #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Supplier ID"}, "Attribute", "Value"),
        #"Filtered Rows" = Table.SelectRows(#"Unpivoted Columns", each ([Value] <> "")),
        #"Grouped Rows" = Table.Group(#"Filtered Rows", {"Value"}, {{"Data", each _, type table [Supplier ID=nullable number, Attribute=text, Value=text]}}),
        Custom1 = Table.SelectRows(#"Grouped Rows", each List.Count(List.Distinct([Data][Attribute]))>1),
        #"Added Index" = Table.AddIndexColumn(Custom1, "Duplicate Group", 1, 1, Int64.Type),
        #"Added Custom" = Table.AddColumn(#"Added Index", "Duplicate List", each Text.Combine(List.Transform([Data][Supplier ID],each Text.From(_)),",")),
        #"Expanded Data" = Table.ExpandTableColumn(#"Added Custom", "Data", {"Supplier ID"}, {"Supplier ID"}),
        #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Supplier ID"}, #"Expanded Data", {"Supplier ID"}, "Expanded Data", JoinKind.LeftOuter),
        #"Expanded Expanded Data" = Table.ExpandTableColumn(#"Merged Queries", "Expanded Data", {"Duplicate Group", "Duplicate List"}, {"Duplicate Group", "Duplicate List"})
    in
        #"Expanded Expanded Data"

    Output:

      It works super great and give me idea. But it would 100% fit the requirement as this is stored in the query. 

      It must be dynamic based on the filter the end user will define. 

       

      Let's assume I have a Active/Not Active dimension : 

       

      Supplier IDStatus

      1Active
      2Not Active
      3Active
      4Not Active
      5Not Active
      6Not Active
      7Active
      8Active
      9Active
      10Active

       

      Based on the above, the result should remove all the Not Active prior to attirbute a group and define the duplicate list. 

      Reason why I was looking to a measure.
