    Hi TM,

     

    I can only agree with itchyeyeballs: Grouping in combination with a MAX function should solve your problem. I copied your table into Excel and then pulled it into Power Query. My script looks like this 

     

    let
    Source = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
    #"Change Type" = Table.TransformColumnTypes(Source,{{"Sales Order            ", type text}, {"  Version number", Int64.Type}}),
    #"Group Rows" = Table.Group(#"Change Type", {"Sales Order            "}, {{"HighestVersionNumber", each List.Max([#"  Version number"]), type number}})
in
    #"Group Rows"

    The result is the following:

     

     

     

     

     

     

    Hope that helps.

     

    Regards,

    Lars

I typed out a soultion for using the group by functionality (either in Access or power query) to create a lookup table, using the max function to only return the highest version number.

 

May be a way to go if TM doesn't wan't the other order data in his model at all I suppose.

itchyeyeballs you are right since if not using old data anywhere else, this can help navigating to data model and also performance, specially if the fact table contains millions of rows.
