Conditional Column, IF statement or something else?

Hello, 

I'm stuck. I have the above data in a table below.

I need to look at Result 2 against Result 1. If Result  is better (UP), Worse (DOWN) or the same (SAME) then I need a conditional column of IF statement or something else to show in the 'Result' Column.

 

Results - Good being the best, then Satisfactory, Poor and Very Poor.

 

Thank you! 🙂

        Source = your_table,
        score = [Very Poor = 1, Poor = 2, Satisfactory = 3, Good = 4],
        res = {"DOWN", "SAME", "UP"},
        result = Table.AddColumn(
            Source, 
            "Result", 
            (x) => res{Value.Compare(Record.Field(score, x[Result 2]), Record.Field(score, x[Result 1])) + 1})
    in
        result

    you can edit this step and add/remove conditions - don't forget to keep correct order from best (lowest value) to worst.

     

     

    Result

     

    let
        DataTable = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45Wcs/PT1HSUQpOLMksTktMLskvqlSK1YlGFdBRCsjPL8ImjqEPrBC3erB1IPGw1KJKBXTFUMcg5JAEITpjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Result 1" = _t, #"Result 2" = _t]),
        ConditionTable = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45Wcs/PT1HSUTJUitWJVgpOLMksTktMLskvqgQKGoEFA/Lzi4AcYzAnLLWoUgEqYqIUGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Condition = _t, #"Order Best to Worst" = _t]),
        ConditionTableChangedType = Table.TransformColumnTypes(ConditionTable,{{"Order Best to Worst", Int64.Type}}),
        MergedQueriesRes1 = Table.NestedJoin(DataTable, {"Result 1"}, ConditionTableChangedType, {"Condition"}, "Res1Value", JoinKind.LeftOuter),
        ExpandedRes1Value = Table.ExpandTableColumn(MergedQueriesRes1, "Res1Value", {"Order Best to Worst"}, {"Res1Value"}),
        MergedQueriesRes2 = Table.NestedJoin(ExpandedRes1Value, {"Result 2"}, ConditionTableChangedType, {"Condition"}, "Res2Value", JoinKind.LeftOuter),
        ExpandedRes2Value = Table.ExpandTableColumn(MergedQueriesRes2, "Res2Value", {"Order Best to Worst"}, {"Res2Value"}),
        Ad_Result = Table.AddColumn(ExpandedRes2Value, "Result", each if [Res1Value] < [Res2Value] then "UP" else if [Res1Value] = [Res2Value] then "SAME" else "DOWN", type text),
        RemovedColumns = Table.RemoveColumns(Ad_Result,{"Res1Value", "Res2Value"})
    in
        RemovedColumns

      Hi AlienSx , Thank you. It seems simple but how to I incoporate this into my table which already has many applied steps? TIA

        lennox25 create blank query, copy and paste my code, replace your_table in my code with the name of your query - the one with many steps (it's name is on the left pane in PQ Editor)

      Hi dufoq3 -  Im unsure how to do this? I have created a 'Condition Table' but have now idea how to work this with my orignal table where there is already many applied steps?

        Hi, have you read note below my post? Keep in mind that in this case Source is DataTable (in my query).
