Tasks Creation Mode 

In Microsoft Project 2010, you can create tasks in two different modes: Auto Scheduled or Manually Scheduled. To successfully integrate tasks between Microsoft Project 2010 and PPM, all Microsoft Project 2010 tasks must be created in Auto Scheduled mode.

If a task is created in Auto Scheduled mode, data in task date and duration fields are validated by Microsoft Project and all tasks can be successfully integrated with PPM.

If a task is created in Manually Scheduled mode, data in task date and duration fields are not validated by Microsoft Project. PPM considers this data to be invalid and does not integrate the data. To successfully integrate all task data, the task must be changed to Auto Scheduled mode.

To change a task's mode, update the Task Mode field.

To set the default task creation mode for new tasks that are added to an existing project, click on the New Tasks menu at the bottom of the work plan window and select Auto Scheduled.

To set the default task creation mode for new projects, go to the File tab and select Options. Select Schedule and then set the New tasks created field to Auto Scheduled.
