Hello,
I have an excel table I'm bringing into Power BI. I'm trying to figure out how to keep only the rows with the most recent date (Oil Change Date).
Here is an example of the table:
Here is an example of whayt my results should look like once properly manipulated:
Is this something a combination of transformation operations in Edit Query can handle? I'm still learning Power BI.
Thank you in advance!

Hi @AW1976NOVA
In edit queries,
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcssvSlHSUTLVt9Q3MjA0UIrViVZy8g0HClnqG4KEjMFCIanFOYlAQUMDfSOwsDlY2DkjtawSrN0UKGhgARaEGmmuD1JsYGiIotLQECJsYIlirjFUMcQEr9TUApBafWOQmCWyqUD9xjBjYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Group = _t, #"Oil Change Date" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Group", type text}, {"Oil Change Date", type date}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Group"}, {"AllRows", each _, type table [Group=text, Oil Change Date=date]}),
RankFunction = (tabletorank as table) as table =>
let
SortRows = Table.Sort(tabletorank,{{"Oil Change Date", Order.Descending}}),
AddIndex = Table.AddIndexColumn(SortRows, "Rank", 1, 1)
in
AddIndex,
AddedRank = Table.TransformColumns(#"Grouped Rows", {"AllRows", each RankFunction(_)}),
#"Expanded AllRows" = Table.ExpandTableColumn(AddedRank, "AllRows", {"Oil Change Date", "Rank"}, {"AllRows.Oil Change Date", "AllRows.Rank"}),
#"Filtered Rows" = Table.SelectRows(#"Expanded AllRows", each ([AllRows.Rank] = 1))
in
#"Filtered Rows"

This can be done without editing M code. Group on "Member ID" and select Max of "Oil Change Date" call it "Max Date", and add aggregate level "expansion" including all rows. Expand, and add conditional column "Latest?". Compare "Oil Change Date" with "Max Date" if equal enter "latest", otherwise "null". Filter on "latest" in column "Latest?". If necessary delete columns "Max Date" and "Latest?"

Few ways.
In visualization take the max of date and HP.
Second
you can create a summarize table
summarize(table,table[group],table[member id],table[color],table[max speed],"Oil change date",max(table[Oil change Date]),"HP",max(HP))
