ETC on a Task with Fixed Loading Pattern is changed

Products

• Clarity PPM SaaS

Issue/Introduction

Fixed loading pattern ETC automatically moves / spreads when you change the task finish date.


Steps to Reproduce: 

1. Create a project.
2. Add a resource to the project.
3. Create a one month task.
4. Assign the resource to the task.
5. Set the loading pattern to Fixed.
6. In the assignment weekly ETC edit the etc to 20 hours in all four weeks.
7. Now edit the task finish date and move it out one week.

Expected Result: On fixed duration tasks do not shift the ETC. 
Actual Result: The ETC spreads evenly from task start to finish so now the first four weeks are not what you entered of 20 hours each.

Cause

This is reported as Defect DE53353.

Environment

Clarity PPM 15.x

Resolution

After reviewing it, SE decided that no changes will be implemented on the product as part of this Defect.

When manually entering and updating ETC segments, changing the dates on the Task will take all assignments and reset the ETC curve data.
This behaviour has always worked in this manner.

To make a change in the behaviour for a manual update to the Task Dates and how it affects the assignments would require an enhancement to the product. 
As an alternative, it would be possible to use PPM Gantt or OWB/MSP to schedule changes in Tasks. 

Additional Information

There might be some confusion on the purpose and use of the Assignment Loading Pattern.  This setting is used for the computations from auto-scheduling through PPM Gantt.
