Issue/Introduction

When Autoscheduling in the Clarity Gant or Open Workbench (OWB), all ETC is getting scheduled for one day for some assignments if loading pattern is set to Front

STEPS TO REPRODUCE 

1. Create a project with a 2 month span (make sure it goes into the future)
2. Add one team member to the project
3. Set the resource's Default Allocation to 0%
4. Create allocation segments for the resource:
   • On the Team tab, click on the properties icon next to the resource
   • Add segments under the Allocation section (example of segments used below)
     
     • 11/14/17 - 11/22/17 @ 35% allocated 
     • 11/23/17 - 12/6/17 @ 40% allocated 
     • 12/7/17 - 12/29/17 @ 0%
5. Create a task (Task dates can be the same as project dates or a smaller subset of those dates)
6. Assign the team member to the task with the following criteria:
   • Loading Pattern: Front 
   • Make sure the assignment dates are more than one day (including a time frame in the future)
   • Make sure the ETC is more than 8 hours
7. Launch the PPM Gantt for the project and Autoschedule with Options
8. Uncheck all options and leave the Autoschedule Date defaulted to the current date

Expected Results: Auto schedule will spread hours based on allocation segments or at least not all on the first day 

Actual Results: All hours are placed on first day

Environment

Applies to all supported releases.

Cause

This one was reviewed by Development as DE37664 and determined to be working as designed for Front loading pattern.

Resolution

This issue happens when a resource has a default allocation of 0% and there isn't enough allocated hours for the resource in the non-zero allocation periods for the task to be scheduled. Autoschedule will attempt to schedule the task into the zero portion of the allocation, resulting in the one-day duration.

Additional Information

Reference:

• OWB or Gantt - Autoscheduling with Uniform pushes tasks dates and ETC out
• Autoscheduling is Changing the Task Date even though there are no Dependencies or Assignments
