As Late As Possible (ALAP) is a Adobe 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 Use task predecessors.

As Late as Possible is the default constraint if a project uses a schedule mode of Schedule from Completion Date and system or group default for the Start Date of a task is Based on the Project Planned Date.

For information about where to set the default Constraint for a new task, refer to Configure system-wide task and issue preferences.

For information about how to update the Task Constraint on a task, see Update the Task Constraint of a task.

The difference between Latest Available Time and As Late As Possible

The Latest Available Time constraint differs from the As Late As Possible constraint when the following criteria exist:

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

In this situation:

  • Latest Available Time: Using the Latest Available Time constraint on the predecessor task gives priority to flexible constraint of the successor.

    Example: For example, Task A is a predecessor to Task B. Task A has the Latest Available Time constraint and Task B has the As Soon As Possible constraint. In this situation, Task A 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 predecessor task gives the priority to the predecessor task.

    Example: For example, Task A is a predecessor to Task B. Task A has the As Late As Possible constraint and Task B has the As Soon As Possible constraint. In this situation, Task A is scheduled as close to the end of the project as possible.
