Sum up undefined number of columns using wildcard

Hi,

 

I'm trying to add a custom column using the sum of a large (undefined) number of previous columns.

Based on a similar use-case I've read about I was trying the following code:

The idea is to list all the columns beginning with "Id_" and using this list to add in the "add" statement.

Using this code I'm generating the list:

temp_adding_column2.JPGtemp_adding_column3.JPG

The following Error occurse :

temp_adding_column4.JPG

But also adapting to code to:

  SumRows = Table.AddColumn(#"Pivoted Column", "Addition", each (ColumnsToSum))

or   SumRows = Table.AddColumn(#"Pivoted Column", "Addition", each ({ColumnsToSum}) is not successful

 

Any ideas if this could work and if I have a mistake in my code or does this "using a list to add a large number of columns" not work at all.

appreciate some feedback Smiley Happy

Re: Sum up undefined number of columns using wildcard

Hi @fishboneox,

 

Add an [Index] first.

Add a custom column like this:

= Table.AddColumn(#"Added Index", "Total", each List.Sum(List.Select(Record.FieldValues(#"Promoted Headers"{[Index]}),each _ is number)))
