The Planned Completion Date is the date a task is scheduled to be completed within the project plan. When an assignee needs to adjust the timeline for a task that is not yet finished, they must update this field. This date is the primary driver for the project schedule, affecting dependencies and the overall project timeline displayed on tools like the Gantt chart. It represents the official, scheduled end date for the work item.

A. Actual Completion Date: This date is automatically recorded by the system when the task's status is changed to a 'Complete' equivelant. It is a historical record, not a future plan.

B. Commit Date: This is a date manually set by a user to indicate a personal promise to complete the work. It operates independently of the project's calculated schedule.

D. Projected Start Date: This date is a system-calculated forecast of when a task might begin, based on predecessor progress and other factors. It is read-only and cannot be updated by an assignee.

1. Adobe Workfront Documentation

"Overview of the Planned Completion Date for tasks." This document states

"The Planned Completion Date is the date when the task is scheduled to be complete... You can manually modify the Planned Completion Date of a task when the Task Constraint is different from As Soon As Possible and As Late As Possible." This confirms it is the updatable

scheduled completion date.

2. Adobe Workfront Documentation

"Overview of the Actual Completion Date." This source clarifies

"The Actual Completion Date is the date and time when a work item was completed. Adobe Workfront automatically populates this field when the status of the work item changes to a status that equates with Complete." This confirms it is an automatically populated

historical field.

3. Adobe Workfront Documentation

"Update the Commit Date for a task." This article defines the Commit Date: "The Commit Date is the date you promise to complete a work item." This distinguishes it from the formal Planned Date.

4. Adobe Workfront Documentation

"Projected Dates overview." This document explains

"Projected Dates are Adobe Workfront’s best guess as to when a task... will be completed... You cannot manually edit the Projected Dates of tasks." This confirms the field is read-only and a system forecast.
