Delete Attribute Rule (Data Management)—ArcGIS Pro

Summary

Deletes one or more attribute rules from a dataset.

This tool requires an exclusive schema lock on the input table.
If you specify both a rule name and a rule type when running this tool, upon execution, the tool will verify that the type of rule specified matches the rule type specified. If they do not match, the rule will not be deleted.
