Sampling in power query

[Anonymous]

Hello everyone!

I would greatly appreciate your help in building this formula in power query. I need to number those cells that are above a threshold (25k here). I achieve this in excel by taking the max till the previous row and add 1 to it, as shown in the screenshot. TIA!

Hi @Anonymous 

There are ways to do it, if you have duplicated numbers in the balance and many rows, this is one way

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrY0MDBQitWJVjI3hLGMYbSpAUzIEEobmYFFYgE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Value", Int64.Type}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1, Int64.Type),
    below25 = Table.SelectRows(#"Added Index", each ([Value] <= 25000)),
    above25 = Table.AddIndexColumn( Table.SelectRows(#"Added Index", each ([Value] > 25000)),"result",1,1),
    Custom1 = Table.Combine({ above25,below25}),
    #"Sorted Rows" = Table.Sort(Custom1,{{"Index", Order.Ascending}}),
    #"Removed Columns" = Table.RemoveColumns(#"Sorted Rows",{"Index"})
in
    #"Removed Columns"
