Additional information about due date for an alert task
You can set the due date and lead time for an alert task.
Set the due date for an alert task in one of the following ways:
Set the target duration
The due date for the alert task is calculated as the target duration for the job. If you set the lead time, the due date for the alert task is target duration + lead time.
For example, if the target duration of an alert task is 4 hrs, the lead time is 2 hrs and the milestone becomes available at 12:00; then the due date of the alert task is 18:00 (depending on the Business Calendar).
If the user takes the task at 13:30 and completes it by 17:30, the task is not overdue. However, if the user takes the task at 16:00 and completes at 20:00, the task is overdue by 2 hours.
Use a variable
The due date for the alert task is calculated as the value given for the due date. If you set the lead time, the due date for the alert task is variable +/- lead time.
Use a milestone
The due date for the alert task is calculated as the selected milestone. If you set the lead time, the due date for the alert task is milestone +/- lead time.
For example, create a milestone, Goods Delivered with a value, 17-02-2013 17:00. If the alert task Final Check (target duration = x variable) must be raised 1 hour before the milestone of Goods Delivered, the lead time is set to -1 hour. However, if the alert task Check Goods Received must be completed 1 day after the milestone Goods Delivered, the lead time is set to +1day.
