As Late As Possible

Using the As Late As Possible Task Constraint

As Late As Possible (ALAP) is a Workfront Task Constraint which places the completion time of the task as close to the end of the project as possible.

Using this constraint may cause predecessor or dependent Tasks to be rescheduled.
For more information about predecessor relationships, see "Using Predecessors."

As Late as Possible is the default constraint if a project uses a schedule mode of Schedule from Completion Date.

To update the Task Constraint to As Late As Possible: 

  1. Navigate to a task whose Task Constraint you want to update.
  2. Click Edit Task.
  3. In the Overview section, expand the Task Constraint drop-down menu.
  4. Select As Late As Possible.
  5. Click Save Changes

Understanding the Difference between Latest Available Time and As Late As Possible

[! This section is duplicated in "Latest Available Time"]
The Latest Available Time constraint differs from the As Late As Possible constraint when the following criteria exist:

  • The project is scheduled From Completion
  • Tasks in the project have a predecessor relationship
  • The predecessor task has a flexible task constraint

In this situation:

  • Latest Available Time: Using the Latest Available Time constraint on the successor task gives priority to flexible constraint of the predecessor.
    For example, Task A is a predecessor to Task B. Task B has the Latest Available Time constraint and Task A has the As Soon As Possible constraint. In this situation, the task is scheduled as close to the start of the project as possible.
  • As Late As Possible: In this scenario, using the As Late As Possible constraint on the successor task gives the priority to the successor task.
    For example, Task A is a predecessor to Task B. Task B has the As Late As Possible constraint and Task A has the As Soon As Possible constraint. In this situation, the task is scheduled as close to the end of the project as possible.
