The Task Mode field indicates whether a task is scheduled manually or
automatically, which gives you the option of deciding how much control
you want over task scheduling in a project. By default, tasks are set
as auto scheduled, with a start date, finish date, and duration
calculated based on inserted fields values.
The Task Mode field
is not included by default. Use Insert column option to insert
and display Task Mode column in views like Gant Chart, Tracking Gant or
Task Sheet view. Task Mode column displays an icon indicating whether a
task, is a manually scheduled task, or an automatically scheduled task.
A task can be Automatically Scheduled or Manually Scheduled.
Automatically Scheduled tasks have Start, Finish and Duration values calculated by Planner based on dependences, constraints, calendars, and other factors.
Manual tasks are tasks with task mode manually scheduled. They
should be used when you want to explicitly set a task's start and finish
dates and not allow it to be changed automatically by the scheduler
based on changes to other tasks.
When a task is in manually
scheduled mode, the Start, Finish, and Duration columns can be blank or
include text values in addition to recognizable dates.
In Planner we support
both Automatically Scheduled and Manually Scheduled tasks.
To change the task mode, click in the Task Mode field. In the list that appears, click Manually Scheduled or Auto Scheduled. You can also select specific tasks, then in the Task Information dialog, General tab, in the Schedule Mode group, select Manually Scheduled or Auto Scheduled.
you want to have in your plan only manually scheduled tasks, before you start planning, set the
manually scheduled mode from Options dialog, Schedule tab. In this way, all the newly
inserted tasks will be set as Manually Scheduled:
