Dynamic data source based on date

[vedansh]

Hi Team,

I have requirement like, from a folder of Excel files i have to pick the data file of MAX datekey files will be maintained in particular fashion i.e, Data Datekey

As mentioned in the image file with max date key to be picked.

I believe it is possible by passing parameter to MQuery. 

Thanks in advance..

Hi @vedansh,

You can use query below to find the Excel file with the maximum date in Power BI desktop: 

let
    Source = Folder.Files("<folder path>"),
    #"Split Column by Delimiter" = Table.SplitColumn(Source, "Name", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Name.1", "Name.2"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Name.1", type text}, {"Name.2", type text}}),   
    #"Changed Type1" = Table.TransformColumnTypes(Table.SplitColumn(#"Changed Type", "Name.2", Splitter.SplitTextByEachDelimiter({"."}, QuoteStyle.Csv, false), {"Name.2.1", "Name.2.2"}),{{"Name.2.1", Int64.Type}, {"Name.2.2", type text}}),
    MaxDte=List.Max(#"Changed Type1"[Name.2.1]),
    FilterRowWithMaxDate=Table.SelectRows(#"Changed Type1",each [Name.2.1]=MaxDte)
in
    FilterRowWithMaxDate

Then you can click Binary to extract data from the Excel file.
