From the History tab of a rule you can track the changes that have been made to the rule over time. By viewing the history, you can see detailed information about each change to the rule, such as when it was changed and by whom. You can also add a memo to history records for future reference, compare historical versions of the rule, and restore a previous version of a rule.
For the rule history, the system converts dates and times from the internal UTC format to your time zone, which might be different from the time zone of the person who updated the rule.
The system saves rule history details as instances of the History-Rule class. By default, instances of the History-Rule class correspond to rows in the pr4_history_rule database table.
If your application implements the optional security audit feature, the History details section can identify which values were added, updated, or removed from a rule or data object.
If the rule was imported from another Pega Platform system by using the Import Archive tool, the History details section reflects only the changes that were made after the rule was imported to this Pega Platform system.
