    Hi Sudheeshp ,

     

    This is my easy-to-understand method.

    1.Add a custom column to return 1 or 0.

    2.Group by as follows.

    3.Add a custom to return the result.

    Best Regards,

    Stephen Tao

See the code here (You will need to replace Source appropriately)

let
    Source = Excel.CurrentWorkbook(){[Name="Table2"]}[Content],
    ListNonBlanks = List.Buffer(List.Transform(List.Select(Table.ToRecords(Source), (x) => x[Promo ID] <> null), (x) => x[Unique Customer])),
    #"Added Custom" = Table.AddColumn(Source, "ID VFP Customer", each if List.Contains(ListNonBlanks, [Unique Customer]) then "Y" else "N")
in
    #"Added Custom"
