From the Task Form Menu select FILE > SHOW HISTORY
Critical TeamLeader events are tracked in TeamLeader History (Also referred to as the log). To view History double click on a specific task and you will be in the Task Form, then click the History icon on the toolbar (looks like a sundial) or click FILE > SHOW HISTORY to display information. The keyboard shortcut is Ctrl+H.
This gives you an audit trail of each task that can be viewed internally by TeamLeader or with external reporting tools.
Certain events such as Start Date and Due Date changes, or marking a task as Incomplete or Cancelled require a narrative comment. This comment becomes part of the audit trail.
The following actions will result in a new entry being added to the history of a task: Creation, Assignment, Forwarding, Completion of a lifecycle stage, Change to Start Date, Due Date, or Description, Completing a task, Canceling a task, Closing a task as Incomplete.
