Simple SUM of two columns not working (only null values returned)

Hi,

 

I am having a strange problem in the query editor (in Power BI). I want to add a new column that is the SUM of two columns in the same table:

It's really strange, if the formula for PASok is just a SUM of the other 2 columns that have some values, how can the new column only return null values? any idea what can be going on here?

 

Thank you very much

Re: Simple SUM of two columns not working (only null values returned)

The + operator is returning a null because the [PAS] field is null ( number + null = null). This behavior is standard for all operators within PQ (+,-,/,*) and sql. You can override this behavior with List.Sum. List.Sum ignores nulls by definition.

 

List.Sum( { [Services Proactive], [PAS] } )
