Powerquery filter only most recent data rows

Hi Anonymous ,

Try this:

Method1:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtA3NNQ3VNJRMlSK1UGIGAFFjJBEDMBqjFFEQGpMECKWYCWmyAIgFWZKsbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Value", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Date.IsInCurrentMonth([Date])),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Custom] = true)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Custom"})
in
    #"Removed Columns"

Method2:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtA3NNQ3VNJRMlSK1UGIGAFFjJBEDMBqjFFEQGpMECKWYCWmyAIgFWZQAUOgvBFYiblSbCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Value", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each (Date.Year(DateTime.LocalNow())-Date.Year([Date]))*12 + Date.Month(DateTime.LocalNow()) - Date.Month([Date])),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each [Custom] < Recent_N_Month),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Custom"})
in
    #"Removed Columns"

BTW, .pbix file attached.

Best regards
