When users cannot edit a traditionally versioned feature dataset after a new feature class is added, the feature dataset must bere-registered as versioned.

1. Why Re-Register as Versioned?

Adding a feature class to a versioned feature dataset requires re-registering the entire feature dataset for versioning.

This step ensures that the new feature class is included in the versioning system and can participate in versioned workflows.

2. Why Other Steps Didn't Resolve the Issue?

Checked Permissions: Correct permissions do not address the need to re-register after adding a feature class.

Checked Connection File: Ensuring the connection file uses traditional versioning does not resolve missing registration.

Rebuilt Indexes and Statistics: While this improves performance, it does not affect versioning.

3. Why Not Other Options?

Connect as Data Owner and Edit Data:

Even as the data owner, edits would not be possible until the feature dataset is re-registered.

Unregister the Feature Dataset as Versioned:

Unregistering would delete the versioning information, potentially causing data loss in the delta tables.

Steps to Re-Register the Feature Dataset as Versioned:

OpenArcGIS Proand connect as the data owner.

Right-click the feature dataset and selectManage > Register As Versioned.

Choose the option toPreserve edits to base tables(if required).

Save and test edits on the feature dataset.

Conclusion:

The administrator shouldre-register the feature dataset as versionedto include the newly added feature class and resolve editing issues in the traditionally versioned environment.
