Constraints are the rules set on the tasks which help you to force the start or finish dates of the task. The advantage of entering constraints is that Celoxis does not allow the schedules to conflict with the specified Constraints and warns you accordingly, thereby avoiding any overlapping of tasks. The following constraint types are supported:
As Soon As Possible (ASAP)
When you set ASAP constraint for your tasks, Celoxis schedules the start date of such tasks to start on the project start date i.e start date of a task with ASAP constraint = start date of the project.
As Late As Possible (ALAP)
When you set As Late As Possible constraint for your tasks, Celoxis schedules the task to start as late as it can (Project's deadlineplanned finish date) without delaying subsequent tasks.
