Read-only, except when the task is created. The TASK_START_DATE and TASK_FINISH_DATE fields are calculated by the Project Server scheduling engine. The scheduling engine calculates the start date based on the task dependencies, the project calendar, and other task constraints. If resources are assigned, the scheduling engine also considers the resource calendar and assignment units.
