Required field parameter not working

ChaceCarpenter — Thu, 10 Apr 2025 15:20:31 GMT

I created a feature class with a required field, but there is an issue. When I add a feature and I don't fill this field; the system lets me add the feature even though the required field is empty. I want any feature that is added to the data set to always have this field filled for data quality reasons. Ps, I am working in a local geodatabase if that matters. It seems that making a field required only makes it so the field cant be deleted. Is there a way to prevent the creation of a feature if a field isn't filled?

short of doing a query on the required field for any value that is not None and using the GetCount tool (which should return a 0 value if there is nothing there)

Get Count (Data Management)—ArcGIS Pro | Documentation

The question becomes, why do you want a required field prior to creating a feature and putting a value in it? Perhaps elaborating on the requirement would help

I want to make sure others users cant add a feature without filling this field. Its a field that should never be blank. So I was trying to validate the data that other user may enter into the dataset

There's a couple workflows that would get you close:

1. You can configure the feature template to prompt for attributes on 1 or more attribute fields. Unfortunately, this would still allow for NULL values. Configure a feature template—ArcGIS Pro | Documentation
2. If features already exist in the feature class to be edited, you cannot uncheck the "Allow Nulls" item in the Fields Designer FAQ: Is It Possible to Uncheck the Allow NULL Check Box When Editing the Attribute Table i
3. If you can recreate the feature class with no data in it - then yes, you can configure a field to not allow NULL values - Problem: Unable to Configure Fields to Ensure Null Values Are Not Allowed in ArcGIS Field
4. You could create a constraint attribute rule that does not allow for Null values - Attribute rule script expression examples—ArcGIS Pro | Documentation
