    Hi JoMont,
    Hope you are doing well.

     

    Open advanced editor in power query and copy paste the below M-code.

    Duplicate Entry is removed and all columns are retained.

     

     

    let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Medical Registration Number" = _t, #"Discipline Type" = _t, #"Facility Type" = _t, #"Start Date" = _t, #"End Date" = _t, State = _t, MMM = _t, #"Discipline Group" = _t, #"FTE equivalent" = _t]),

    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Medical Registration Number", type text}, {"Discipline Type", type text}, {"Facility Type", type text}, {"Start Date", type date}, {"End Date", type date}, {"State", type text}, {"MMM", type text}, {"Discipline Group", type text}, {"FTE equivalent", type number}}),

// Sorting by Medical Registration Number and Start Date is important here.
// Without applying sorting logic, sometimes gives you different result.

Sort_Logic = Table.Sort(#"Changed Type",{{"Medical Registration Number", Order.Ascending}, {"Start Date", Order.Ascending}}),

Duplicate_Logic = Table.Distinct(Sort_Logic, {"Medical Registration Number", "Discipline Type", "Facility Type", "Start Date", "End Date", "State", "Discipline Group", "FTE equivalent"}),


Group_Logic_1 = Table.Group(Duplicate_Logic, {"Medical Registration Number", "Discipline Type","Facility Type", "State", "MMM", "Discipline Group"}, {{"AllRows", (x) => x}}, GroupKind.Local),

//Assuming your data has continuous date period where a medical number is doing two different placements in the same discipline.
// If Date range is not continous, sometimes gives you different result.

Transform_Logic = Table.TransformColumns(Group_Logic_1, {{"AllRows", (x) => Table.TransformColumns(x, {{"Start Date", (y) => List.Min(x[Start Date])},{"End Date", (y) => List.Max(x[End Date])}})}}),

Combine_Logic = Table.Combine(Transform_Logic[AllRows]),

Group_Logic_2 = Table.Group(Combine_Logic, {"Medical Registration Number", "Discipline Type", "Facility Type", "Start Date", "End Date", "State", "MMM", "Discipline Group"}, {{"FTE equivalent", each List.Sum([FTE equivalent]), type nullable number}}),
Output = Table.TransformColumnTypes(Group_Logic_2,{{"Medical Registration Number", type text}, {"Discipline Type", type text}, {"Start Date", type date}, {"End Date", type date}, {"FTE equivalent", type number}})

Hi JoMont, another solution:

You can delete CHangedTypeEU and ChangedTypeUS steps if you do not need them.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("rZGxCoMwEIZfJWQWTS4x6twW6SDt0kkcUj1KQCJoKPj2jVaKdrBLt/9yfB//kbKknAa0OB0Zl8KnHC32uiUFNqY2Fv0TjyPOImAw7SFdDTxMFa2CksIvB2QrTEWMT1lOCjYLxCKQWeLT5T44dL2pB6JtQ/LRaqy7tnuMfpkutHhXY/IzsDCeZfIPMrG44sWlIPPpqv1JepbtNpEzqzbsbg+uVjhAxJIvV7Jxna1DO5gnkoPukdyscRMnNtz6o4BW1Qs=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Index = _t, #"Medical Registration Number" = _t, #"Discipline Type" = _t, #"Start Date" = _t, #"End Date" = _t, #"FTE equivalent" = _t]),
    ChangedTypeEU = Table.TransformColumnTypes(Source,{{"Index", Int64.Type}, {"Start Date", type date}, {"End Date", type date}}),
    ChangedTypeUS = Table.TransformColumnTypes(ChangedTypeEU,{{"FTE equivalent", type number}}, "en-US"),
    GroupedRows = Value.ReplaceType(Table.Combine(Table.Group(ChangedTypeUS, {"Medical Registration Number", "Discipline Type"}, {{"All", each _, type table}, {"T", each Table.FromRecords({_{0} & [Start Date = _{0}[Start Date], End Date = List.Last([End Date]), FTE equivalent = List.Sum([FTE equivalent])]}) , type table}})[T]), Value.Type(Table.FirstN(ChangedTypeUS, 0))),
    ReplacedIndex = Table.ReorderColumns(Table.AddIndexColumn(Table.RemoveColumns(GroupedRows,{"Index"}), "Index", 1, 1, Int64.Type), Table.ColumnNames(GroupedRows))
in
    ReplacedIndex
