% Complete not calculating for Child Tasks that are Milestones

Issue/Introduction

Issue:

A Summary Task's % Complete is not updating based on it's child task even though the % Complete Calculation Method is set to 'Effort' for the project and the 'Update % Complete' job has been run.

Scenario: The system is set to automatically calculate task completion status on effort basis. When a task has sub-tasks which have effort booked against them, the task completion status of the sub-task as well as the task are calculated correctly. When a task has only a milestone as sub-tasks and the % completion status of the milestone is changed manually (as no efforts can be booked on a milestone) this is not reflected in the task. E.g. the nested milestone is set to 100%, but the next-level task still shows 0% completion.

Steps to Reproduce:

1. Create a project and set the % completion method as "effort".
2. Create one Key Task and one Milestone task under that project. 
3. Open the project in the PPM Gantt view and indent the Milestone task under the Key task. 
4. Now the key task is the parent and the Milestone is the child. 
5. Since it is a Milestone, the % complete can be set as 100 manually. 
6. Do the same and save the change.

Expected result:

The % complete for the parent Key Task shows as 100.

Actual result: 

The % complete for the parent Key Task remains 0.

Cause

Working as designed

Environment

Release: All Supported Releases
Component: PROJECT MANAGEMENT

Resolution

Sustaining Engineering reviewed and determined that this is not a bug. The summary task does not pull % Complete from any of its child tasks that are milestones. Tasks that are milestones cannot have work, so the parent summary task's % Complete does not update based on the child tasks.
