Re: load latest date record

Hi @vengadeshpalani,

 

What is your data source? For some databases like SQL Server, you can add customized SQL Query to "SQL statement" when creating data connection to filter latest date records within group and only load those records into desktop.

 

However, for some other data source types like Excel, above method doesn't work. You may have to load all data records into desktop first, then apply data transformation via Power Query to specify how many rows you would like to keep from the original dataset. Reference: Grouping in Power Query; Getting The Last Item in Each Group

let
    Source = Excel.Workbook(File.Contents("C:\Users\xxxx\Desktop\Sample Data.xlsx"), null, true),
    Sheet4_Sheet = Source{[Item="Sheet4",Kind="Sheet"]}[Data],
    #"Promoted Headers" = Table.PromoteHeaders(Sheet4_Sheet, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Interview Date", type date}, {"Candidate ID", type text}, {"Round", type text}, {"Interviewer", type text}, {"Result", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Candidate ID", "Round"}, {{"all data", each _, type table}, {"Latest date", each List.Max([Interview Date]), type date}}),
    #"Expanded all data" = Table.ExpandTableColumn(#"Grouped Rows", "all data", {"Interview Date", "Interviewer", "Result"}, {"all data.Interview Date", "all data.Interviewer", "all data.Result"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded all data", each [all data.Interview Date] = [Latest date]),
    #"Renamed Columns" = Table.RenameColumns(#"Filtered Rows",{{"all data.Interview Date", "Interview Date"}, {"all data.Interviewer", "Interviewer"}, {"all data.Result", "Result"}}),
    #"Removed Columns" = Table.RemoveColumns(#"Renamed Columns",{"Latest date"})
in
    #"Removed Columns"
