Aggregate table for dataflow

I'd like to aggregate a table for my dataflow.  The table is down below. I'd like to have:

  • for each distinct REFOBJECT ID,
  • the latest PMCVALIDFROM,
  • and corresponding PMCRENTAMOUNT + PMCSCORINGPOINT

Can I use the option 'Group by' and if so, how?

Hello @PZUDGW 

 

use Table.Group and within the group-function Table.Max to get your desired result. Here an example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTI01jM01DMyADHBOFYHKmEBlzACY7iEqZ6hEUTCGIxBEk5AloGFnoGhnqElilEwCSOIBMIoJ4jlBsYQCahRsQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"REFOBJECT ID" = _t, PMCVALIDFROM = _t, PMCRENTAMOUNT = _t, PMCSCORINGPOINT = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"REFOBJECT ID", type text}, {"PMCVALIDFROM", type date}, {"PMCRENTAMOUNT", Int64.Type}, {"PMCSCORINGPOINT", Int64.Type}}, "de-DE"),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"REFOBJECT ID"}, {{"LastVALIDFROMROW", each Table.Max(_, "PMCVALIDFROM"), type record}}),
    #"Expanded LastVALIDFROMROW" = Table.ExpandRecordColumn(#"Grouped Rows", "LastVALIDFROMROW", {"PMCVALIDFROM", "PMCRENTAMOUNT", "PMCSCORINGPOINT"}, {"PMCVALIDFROM", "PMCRENTAMOUNT", "PMCSCORINGPOINT"})
in
    #"Expanded LastVALIDFROMROW"

 

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
