Manage a task constraint

Edit, reassign or delete a task constraint in the Lookahead, and read the delay icons.

Manage task constraints in the Lookahead. Once a task has constraints, you cannot update its progress until all of them are Done. So keep them up to date.

A constraint has two menus:

  • Detail View: double-click the constraint.
  • Mini Widget: click the constraint once.

In the Detail View you can:

  • Click Edit (pencil icon) at the top to change the name, description, ETA and assignee.
  • Change a step's status, date and assignee: hover over the step and click Edit step. The last step's date is the constraint's due date. See Manage steps under a task constraint.
  • Update comments and attachments.

To delete a constraint, use the Mini Widget. Delete is not in the Detail View.

Edit a constraint

  1. Double-click the constraint (the circle in line with its task).
  2. Click Edit (pencil icon) at the top of the Detail View.
  3. Change the name, description, ETA or assignee.
  4. Click the tick button to save the changes.

Delete a constraint

  1. Click the constraint once.
  2. Click Delete.
  3. Click Delete again to confirm. This cannot be undone.

You see Delete only if you have permission to delete constraints.

Two kinds of delay

A delayed constraint shows a running man icon.

Two delayed constraints, one with an outlined running man and one with a solid red running man

  • Running man with only a red outline: a step is late, but the delay has not moved the activity or task. There is still enough time between the constraint and the activity or task for the ETA.
  • Solid red running man: a step delay has moved the activity or task.

Activity constraints are managed the same way. See Manage an activity constraint.
