ArcGIS Pro- Calculate Fields (Multiple) Respect Null Calculations

Amanda__Huber — Fri, 13 Jun 2025 18:43:46 GMT

Has anyone else seen issues when using the Calculate Fields (Multiple) tool, to calculate fields to NULL. I have tested using both Arcade and Python and the tool says it executes successful, but when viewing the data all the records are still there and are not NULL

Any insight into this would be appreciated.

Thanks,

Amanda Huber

Hi @Amanda__Huber,

Have you tried setting the expression to Null if arcade or None if python? Typically the expression should be set to one of these depending on the language you are using.

I tested RPGIS's suggestion with the expression being Null if arcade and None if python in ModelBuilder as you had in your graphic. Works as expected. Add Null or None to your expression parameter and it should work.
