    Hi Anonymous ,

     

    Create a measure as below:

    Day = 
var _latestday=CALCULATE(MAX('Table'[Date]),FILTER(ALL('Table'),'Table'[Ticket ID]=MAX('Table'[Ticket ID])))
Return
IF(MAX('Table'[Date])=_latestday,MAX('Table'[Date]),BLANK())

    Or a calculated column as below:

    Column = 
var _latestday=CALCULATE(MAX('Table'[Date]),FILTER('Table','Table'[Ticket ID]=EARLIER('Table'[Ticket ID])))
Return
IF('Table'[Date]=_latestday,'Table'[Date],BLANK())

    And you will see:

Hi, Anonymous , you might want to try this solution,

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjRS0lGy1DcyACIgy78gNU8pVgchbggRd87JL05NgciYQGRM0HVAxU2RxWMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Ticket ID" = _t, Date = _t, Status = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Ticket ID", Int64.Type}, {"Date", type date}, {"Status", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Ticket ID"}, {{"Latest", each _{[Date = List.Max([Date])]}}}),
    #"Expanded Latest" = Table.ExpandRecordColumn(#"Grouped Rows", "Latest", {"Date", "Status"}, {"Date", "Status"})
in
    #"Expanded Latest"
