Task constraint ETA

ETA is the number of working days between a constraint's last step and the start of the task. The last step must be due at least that many working days before the start.

• If ETA = 5, the constraint must be cleared at least 5 working days before the task's start date.
• The ETA is set in days, from 0 to 100. The default is 1.
• You can edit the ETA at any time until the constraint is done.
• Changing the ETA never affects the task's start date. It can affect the due dates of the constraint and its steps.
• The minimum ETA is 0. This means the task can start on the same day the constraint is done.

Edit the ETA

1. Double-click the constraint (the circle in line with its task).
2. Click the Pencil (Edit) button.
3. Change the value in the ETA box.
4. Click the tick button to save.
