Create an audit key
Audit keys must be unique within an object class. You cannot create a key that duplicates existing public or preconfigured key of the same type for the same object class. Two audit keys are identical if the value of the Columns attribute is unique.
You can only create audit keys for an object class if the Audit attribute of the object class is set to True.
You can set the Audit attribue simultaneously for all protected and private object classes. Click the Classes node and select Turn Audit On for All Protected/Public Classes or Turn Audit Off for All Protected/Public Classes.
