Hi @grishbuzz 


How the query editor make a merge between both table by the product then expand the sales and delete the previous column.


Check Code below:

    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIEYgM9U6VYnWglJyAbzDWC8J1hfAjXBcg2BvPNgQKxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Product = _t, Sales = _t, Price = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"Sales", Int64.Type}, {"Price", type number}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Product"}, MasterTable, {"Product"}, "MasterTable", JoinKind.LeftOuter),
    #"Expanded MasterTable" = Table.ExpandTableColumn(#"Merged Queries", "MasterTable", {"Sales"}, {"MasterTable.Sales"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded MasterTable",{"Sales"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"MasterTable.Sales", "Sales"}})
    #"Renamed Columns"
