Add auto sequential values using attribute rules in ArcGIS Pro

Summary

This article provides steps to let the newly created features have the next number sequence in a field, such as an ID or index field.

6. Click the Add Rule drop-down and select Add Immediate Calculation Rule.
7. Specify a Rule Name.

NextSequenceValue ('Test')

Note:
When adding an attribute rule, ensure that the Exclude from application evaluation parameter is enabled or set to true.
