You can purge the data that appears in the Audit Trail and Error Log reports. Purging these reports deletes all data that satisfy the search criteria used. For example, if you search for all Audit Trail entries from March 26, 2008 through March 27, 2008, only those records will be purged. Entries earlier than March 26 or later than March 27 will remain in the Audit Trail.
Purged data is removed from CC-SG permanently.
