Conditionally remove duplicates

Hello Community,

 

Is there a way in PowerQuery or Excel to conditionally remove duplicates? 

Very quick context there are employee id numbers, their planned hours for the year, the financial year and Hrs of absence. However the raw lists their yearly hours on every row, i want to only keep one per financial year. 


I've explored the forum and tried using a helper column but have not had any success.

 

Any help is greatly appreciated.

@Anonymous here is the example power query script which you can use to achieve it.

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI0ABFA7BZpaKYUq4MkaoRP1BxV1BhZFKTECCRqgmwCXNQUqyh2E/Cai12tBVa1lljdABSNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Emp = _t, Planned = _t, Hours = _t, Year = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Emp", Int64.Type}, {"Planned", Int64.Type}, {"Hours", Int64.Type}, {"Year", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Emp", "Year"}, {{"Rank", each Table.AddIndexColumn(_, "Rank", 1)}}),
    #"Expanded Rank" = Table.ExpandTableColumn(#"Grouped Rows", "Rank", {"Hours", "Planned", "Rank"}, {"Hours", "Planned", "Rank.1"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Rank", "New Planned", each (if [Rank.1] = 1 then [Planned] else null), type number),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Planned", "Rank.1"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"Hours", Int64.Type}})
in
    #"Changed Type1"

Hi @Anonymous ,
 
First, you can select "pers.no" and "FY" columns in the edit query, then click "Remove rows"→" Remove duplicate".
