Helper I

## insert new calculated field

Hi, I have a table with 2 fields, one is the description and one is the amount related to description.

But in some case our management system can.'t know if the description is equal to "buy" or to "sell" and so, the system insert in the description the value "-1"

 Description Amount Sell 150 Buy 256 Sell 895 Sell 744 Sell 122 Sell 252 Buy 253 Buy 1236 -1 500 -1 300

Now, to our investor I can't show in my report that there are record equal to -1, and so I would to create a new column and take "Buy" or "Sell" when are "Buy" or "Sell", and I would to insert in place of -1 a value related to this calculation:

1) Sum all the "Buy" and all the "sell". In my example:

 Description Amount Sell 2163 Buy 1745

2) and assign the description of the lowest value to -1. So in my example, in the new column there will be in place of -1, Buy.

thank you.

You can do it in a power query with simple steps and one custom column. Past the below code on a Blank Query on the Advanced Editr and check the :

``````let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCk7NyVHSUTI0NVCK1YlWciqtBPKMTM3APKikhaUpMtfcxASZa2hkhMw1MjVCMckYiWdoZAwxWNcQyDM1MEBwjEGcWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Description = _t, Amount = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Amount", type number}}),
#"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([Description] <> "-1")),
#"Grouped Rows" = Table.Group(#"Filtered Rows", {"Description"}, {{"Total", each List.Sum([Amount]), type nullable number}}),
#"Sorted Rows" = Table.Sort(#"Grouped Rows",{{"Total", Order.Ascending}}),
#"Kept First Rows" = Table.FirstN(#"Sorted Rows",1),
Custom1 = #"Changed Type",
#"Added Custom" = Table.AddColumn(Custom1, "Custom", each if [Description] = "-1" then #"Kept First Rows"[Description]{0} else [Description])
in
