Additional information

When editing feature tables that are subject to database behavior (operations on one table affecting another table), it’s now recommended to call these methods (apply or undo edits) on the

object rather than on the object. Using the object to call these operations will prevent possible data inconsistencies and ensure transactional integrity so that all changes can be committed or rolled back.
