Hei,
In Query Editor, I have a table containing a column like below. As weeks passes, data for the new weeks appears:
Week
Wk 2019-01
Wk 2019-02
Wk 2019-01
Wk 2019-03
Wk 2019-04
Wk 2019-02
Wk 2019-01
Wk 2019-03
How do I filter out the n'th highest week. For example, how do I filter, so that only rows with values from the 2nd last week ("Wk 2019-03" in example above) are kept?
Thanks in advance for any help.

@depple,
Add a blank query in Power BI Desktop, then paste the following code into Advanced Editor of the blank query.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCvdWMDIwtNQ1MFTSUTI0UorVQRIzAooZm6CKGWIRMwaKmaLpNQGZZ4JpnpEhpnkmppjmGRkrxcYCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Week = _t, Value = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Week", type text}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Text.End([Week],2)), #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Value", Int64.Type}, {"Custom", Int64.Type}}), #"Sorted Rows" = Table.Sort(#"Changed Type1",{{"Custom", Order.Descending}}), #"Grouped Rows" = Table.Group(#"Sorted Rows", {"Custom"}, {{"newcol", each _, type table}}), #"Added Index" = Table.AddIndexColumn(#"Grouped Rows", "Index", 1, 1), #"Expanded newcol" = Table.ExpandTableColumn(#"Added Index", "newcol", {"Week", "Value"}, {"newcol.Week", "newcol.Value"}), #"Filtered Rows" = Table.SelectRows(#"Expanded newcol", each ([Index] = 2)) in #"Filtered Rows"
