Identifying the 2 most recent days in Power Query

Hello Anonymous 

check out this solution. It involves of creating a list of the 2 latest dates in a date-column. This list is then used to filter the whole table

let
	Source = #table
	(
		{"Date","Column1"},
		{
			{"43466","test1"},	{"43678","test2"},	{"43554","test3"},	{"43819","test4"},	{"43831","test5"},	{"43833","test6"},	{"43838","test7"},	{"43851","test8"},	
			{"43851","test9"},	{"43848","test10"}
		}
	),
    ToDate = Table.TransformColumns
    (
        Source,
        {
            {
                "Date",
                each Date.From(Number.From(_)),
                type date
            }
        }
    ),
    GetListToFilter = List.FirstN
    (
         List.Sort
        (
            List.Distinct
            (
                ToDate[Date]
            ),
            Order.Descending
            
        ),
        2
    ),
    SelectRows = Table.SelectRows
    (
        ToDate,
        (row)=>
        List.Contains
        (
            GetListToFilter,
            row[Date]
        )
    )
in
	SelectRows

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query, or I could create a custom function what makes it easier to apply if you are not used that much to power query.
