Task Finish date changes for non-fixed duration tasks when updating the Start dates manually

Products

• Clarity PPM SaaS
• Clarity PPM On Premise

Issue/Introduction

When manually changing the start date of a task that is not fixed duration, the finish date automatically adjusts after saving retaining the duration. This happens regardless of whether there is an assignment on the task.

Environment

Release : All 

Component : PROJECT MANAGEMENT

Cause

This is working as expected. The fixed flag is not taken into account in manual task date changes, the fixed flag is used for Auto Scheduling.

Resolution

The Fixed Duration setting is used for Auto Scheduling purposes. Manual changes to the Task Dates are independent of the Fixed setting. So, changing only the start date will move the task forward without changing the duration regardless of whether the task is Fixed Duration or not.

Notes: 

• In Classic PPM or Gantt; you can change both dates at the same time before clicking the 'Save' button.
• See Establish Task and Resource Constraints for details on the difference between having fixed checked or not (this is in the Open Workbench (OWB) documentation, but applies to the PPM Gantt auto scheduling as well). Non fixed duration tasks are referred to as Variable Duration tasks)

Additional Information

See Edit Task Duration in the Gantt Chart of the documentation regarding interactive changes you see when you edit the task attributes on the Gantt view
