Users with permission to purge the entire Workflow log can do so by selecting Admin | Workflow Log | Purge All Entries. A Confirmation dialog box is displayed. To proceed with the purge, click Yes. Click No to close the message box and cancel the purge.
CAUTION:
Once you delete information from the Workflow log it is permanently removed from the database.
A Purged Workflow Log action entry is made in the Transaction Log any time a Purge All Entries is performed. The log is also automatically saved in the SYS Workflow Logs Document Type.
When the Workflow log is purged, information is also removed from the Workflow Transaction tab within Document History.
