Tasks

Within a selected project the Tasks tab maintains all the tasks for that project.

A project usually comprises a series of shorter-duration tasks.
You can define an unlimited number of tasks for each project.
Tasks can be multi-level.
Each task's start and end date must be within the start and end date of its parent task or project.
Employees enter labor time for a task, not a project, so at least one task is required to log time. Time entered for a task is also entered in that employee's timesheet.
Employees can be assigned to tasks and are called Members of the task. Tasks assigned to an employee display on the employee's My Task page and on the employee's timesheet, if the task and timesheet date ranges overlap.

Four Types of Tasks

There are four types of tasks you can include in a project:

Task - A standard task.
Summary Tasks - A container task. You cannot assign members and enter time for summary tasks. This supports the project convention of reporting actual work using the lowest level tasks in a project.
Clock Task - Reserved for future use.
Milestones - A zero duration task with only an end date. Milestone tasks mark the completion of a phase in a project. Milestone tasks are typically used with a fixed priced contract to trigger milestone payments. Enabling the Alter From Project option in a fixed price contract adds a milestone task to a linked project each time you add a new milestone payment to the contract.

Note: Unless otherwise noted in the documentation, assume a standard Task is being described.
