Filter column based on two rules

Hi Vialle_Diego ,

Please refer to this step.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Vc9LDoAgDEXRvXRMUiigY1A+UXdg2P82xMEzddaXM7jpfZOz1pEhx47FiswzJRrmA2EB5KzBswdsG+BdgQNg3zVEjoBSAP7fqFXDwgugNUD4N3oHxLlWXgHXpUE1jkOD+uM8aYwH", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Case = _t, #"Opened on" = _t, #"Assignment Group" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Case", Int64.Type}, {"Opened on", type date}, {"Assignment Group", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Case"}, {{"Data", each _, type table [Case=nullable number, Opened on=nullable date, Assignment Group=nullable text]}, {"Max Date", each List.Max([Opened on]), type nullable date}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"Opened on", "Assignment Group"}, {"Opened on", "Assignment Group"}),
    #"Added Conditional Column" = Table.AddColumn(#"Expanded Data", "Custom", each if [Opened on] = [Max Date] then 1 else null),
    #"Filtered Rows" = Table.SelectRows(#"Added Conditional Column", each ([Custom] = 1)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Max Date", "Custom"})
in
    #"Removed Columns"
