    Hi sahgir123 

     

    See if this works for you

    let
    maxDate = List.Max( List.Distinct( ChType[Date])),
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcsrMSyyqVNJR8krMMzIG0gaG+kBkZADkxOogybulJsHljXDIm4DkjaDyJtjlDU0Q8rEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Content = _t, Files = _t, Date = _t]),
    ChType = Table.TransformColumnTypes( Source, {{"Date", type date}}, "nl-NL"),
    AddIsMax = Table.AddColumn(ChType, "IsMax", each if [Date] = maxDate then 1 else 0)
in
    AddIsMax

     

    This gets me the Dates column from the ChType step: ChType[Date]

    It's used in the maxDate variable to retrieve the max value and is used to add the IsMax column

     

    I hope this is helpful
