How to sum null with other digits while not converting it into zeo

[KarolinaUrbaniak]

Hi Community, I am looking for a solution to sum null with other digits. The challenge here is that I cannot transform null into zeros as it's important for me to see if in case that all elements of the calculation are null.

@KarolinaUrbaniak I dont think you can sum NULL value to other numbers without converting into zeros, if you sum NULL to numbers it will become NULL

Try to transform the data so you can use the Summarize tool to Sum, it will work even for Null values.
