Merge rows based on criteria

Hi PhyuLayKhine333 ,

You cant try this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8g8L9vQxMjI0MjIwtLAwNtE1VNJRcgRiI2MgYWygFKuDQ5ETIUVGQDlnkCJzIGGGR5ELsqJYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Model = _t, Price = _t, Quantity = _t]),
    #"Grouped Rows" = Table.Group(Source, {"ID", "Price", "Quantity"}, {{"Rows", each _, type table [ID=nullable text, Model=nullable text, Price=nullable text, Quantity=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Model", each Table.Column([Rows],"Model")),
    #"Extracted Values" = Table.TransformColumns(#"Added Custom", {"Model", each Text.Combine(List.Transform(_, Text.From), ","), type text}),
    #"Removed Columns" = Table.RemoveColumns(#"Extracted Values",{"Rows"})
in
    #"Removed Columns"
