Hi PQ Gurus,

I have a tall order, which I know I would NEVER be able to figure out myself, and am hoping one of you experts could assist. I know the requirements are pretty extensive, but would appreciate ANY help in trying to figure this out.

I have a large data set (small sample below), and I want to have Power Query achieve the following:
Randomly select 5 "Chat_ID"s for every "Support Name", but assign it to a "TM_Name" that ISN'T the existing one. The new TM Name should be added to the "New_TM_Name" column. I also want to make sure that every New TM has a (fairly) equal number of Chat_IDs assigned to them.

Note: I realize the sample below won't have enough records to fully complete the above, so if more sample records are required, please let me know.

I am not sure if each Support_Name should be assigned to the same TM_Name or not, but if every new TM should have the equal (fair) number of assignments then TMs should be different for each chat. According to this assumption, here is my way of solving this puzzle. You might need to adjust the ChatCount and Table1 name values in the code.

The M Code:
Power Query: 
let
    ChatCount = 5,
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    Randomize = Table.AddColumn(Source, "Randomize", each Number.Random()),
    Supports = Table.Group(Randomize, {"Support_Name"}, {{"Data", each Table.Sort(Table.Range(_, 0, ChatCount), "Randomize")}}),
    Data = Table.Buffer(Table.AddColumn(Table.ExpandTableColumn(Supports, "Data", List.RemoveFirstN(Table.ColumnNames(Source), 1)), "New_TM_Name", each null)),
    TMs = Table.AddColumn(Table.FromList(List.Distinct(Source[TM_Name]),Splitter.SplitByNothing(), {"TM_Name"}),"Rate", each 0, Int64.Type), 
    Result = List.Accumulate(
                {0..Table.RowCount(Data) - 1},
                [TMsTable = TMs, DataTable = Data],
                (state, current) =>
                    let
                        Chat = state[DataTable]{current},
                        TM = Table.First(Table.Sort(Table.SelectRows(state[TMsTable], each [TM_Name] <> Chat[TM_Name]), {"Rate"})),
                        TMsUpdate = Table.ReplaceMatchingRows(state[TMsTable], {TM, Record.Combine({TM, [Rate = TM[Rate] + 1]})}),
                        DataUpdate = Table.ReplaceMatchingRows(state[DataTable], {Chat, Record.Combine({Chat, [New_TM_Name = TM[TM_Name]]})}),
                        Result = [TMsTable = TMsUpdate, DataTable = DataUpdate]
                    in
                        Result
            )[DataTable]

The code takes care about the "fair" assignment. You can verify that by looking at the table in the result table (scroll right to see that part).

THank you SO much smozgur! I've waited so long for a solution that I ended up giving up trying to automate this. Yours is an interesting solution and it might be my only option, so I appreciate the time you spent on this! You're a rock star!
