Burndown Column

Hello uthall 

add a custom column with this formula. You have to replace the PreviousStep with the name of your previous step

List.Sum(YourPreviousStep[A])-[A]

Here the complete code to copy into the advanced editor

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlaK1YlWMgGTRmDSFEyag0kLS6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t]),
    YourPreviousStep = Table.TransformColumnTypes(Source,{{"A", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(YourPreviousStep, "B", each List.Sum(YourPreviousStep[A])-[A], type number)
in
    #"Added Custom"

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
