Audit Log Purge Management Utility
The Audit Log Purge Management utility removes large chunks of data by date from the audit logs, using a First-In-First-Out methodology. The data in the audit logs is never individually updated or deleted. The Audit Log Purge Management utility is only available from the Site > Utilities page to ensure that the audit records are purged in their entirety from one or more organizations.

Once the audit records are purged, they are permanently deleted. To preserve the data, it is recommended that you generate and export the content to a spreadsheet prior to purging the audit logs.
The Audit Log Purge Management table provides information about the purged results including the date the records were purged, the user who purged them, the date through which the records were purged, and the number of records in each purge. Click the purge audit log icon at the top of the table to delete audit logs through a specified date. For more information about working with tables, see Using Tables.
When specifying the date through which the audit records will be purged, the site administrator can choose to save the purged records to a Windchill document (wt.doc.WTDocument). These documents are in XML format and the files are listed in the Archived Results column of the Audit Log Purge Management table. You can download the documents and view them using an XML viewer, however, the records are no longer available in the audit tables. For example, if you purge the audit logs through December 31, 2009 and want to create a new query, only events that occurred after the last purged date will be pulled into the security audit reports.
