Task Types

Tasks can be broken-down into a collection of Subtasks within a Parent Task, or converted into a Milestone Task.

Parent Tasks

After a Task is broken down into a Parent Task, it becomes a summary of all its Subtasks. Some properties are controlled by the Parent Task that all Subtasks will inherit:

Parent Task Properties
  • Owner

  • Assignee

  • Folder Code

  • External ID

  • Package

  • Parent


Aside from the inherited properties, Subtasks can have their own individual properties:

Subtask Properties
  • Start

  • Finish

  • Duration

  • Calendar

  • Shift

  • Blockers

  • Subcontractor

  • Labour

  • Plant

  • Location

  • Work Area

  • Notes

  • Comments

  • Documents

  • Related Tasks

  • Activity ID

  • Status

  • Blockers

  • Tags


Standard Tasks and Subtasks can also be converted into Milestone Tasks, or Milestone Subtasks.

Milestone Tasks are unique in the following ways:

  • Ability to have a Target Date, in addition to Start & End dates

  • Do not appear as a ‘bar’ on the Gantt, but instead have their own Diamond shape

  • Are excluded from the Missing Data checks before a new version is created

As Milestones are a Task Type, all Task Properties and associated Task Permissions that are applicable to Standard Tasks and Subtasks also apply to Milestone Tasks and Milestone Subtasks.

However Milestone Tasks do have some special properties:

Milestone PropertyDescription

Target Date

Target Date is a single date that enable projects to track Target Dates against the end date of the Milestone

Publication History

The Publication History section tracks the Milestone's current end date in comparison to the end date in each recent Published Version

Activity Feed

The Activity Feed contains a record of all of a Task’s changes, Comments and attachments (images and documents).

This includes a detailed log of all updated properties and Progress Updates, the User that made the change, and the exact time that the change was made.

You can filter which data to view in the Activity Feed:

All Activity

Task Property changes, Progress Updates, Comments & attachments (images and documents)


Comments and attachments (images and documents)

Dates & Progress

Date changes and Progress Updates


Changes to the state of Blockers and adding/removing Blockers from a task
