Accountants Enterprise with Practice Manager only

In MYOB Accountants Enterprise Practice Manager (AE PM), if you use Schedules, you can add an additional Assignment Task Status.

The Maintenance — Task Status page enables you to add a new task status, define its display order and set the status to display on timesheets.

If you use Jobs, don't add additional Task Statuses.

If you add additional Task Statuses, the Complete status must not be overwritten. Only change the Display Order field.
