I have a table (sample below) where the "Spend Year" columns can vary in number. I need to TRANSFORM these "Spend Year" columns by dividing them by the value in the "Count" column. This needs to be dynamic so that it the number of "Spend Year" columns does not matter.
I was able to find a way to ADD A COLUMN:
Table.AddColumn(#"Previous Step","New Column", each List.Sum(Record.ToList(Record.SelectFields(_,List.RemoveItems(Table.ColumnNames(#"Changed Type"), {"Account", "Billed Month", "Count"}))))/[Count])
But I want the value returned by the division to stay in the respsective column for "Spend Year". Using Table.TransformColumns is resulting in an error, at least the way I've set it up.
Can anyone assist? @ImkeF the M Wizard?
I have a table as such:
