Investment Portal documentation states under the Timeline 'tab': "The Work Breakdown Structure (WBS) in the tab displays only key milestones."
The Sys Property 'com.snc.investment_portal_include_all_tasks' notes:
"When the property is set to false, only the milestone tasks of a project are displayed in the Investment Portal Timeline view." (And OOB, all Milestone type tasks display)
Actual expected behavior: BOTH Milestones and Key Milestone are to be displayed in the Timeline tab when com.snc.investment_portal_include_all_tasks = false
*A documentation request has been created to correct this inaccuracy - the documentation should display: "The Work Breakdown Structure (WBS) in the tab displays only key milestones and milestones"
