In the Clarity PPM New User Experience (UX), if you have more than two Work Breakdown Structure (WBS) levels in a task hierarchy, you are unable to fully edit any task and some tasks are missing.
Steps to reproduce:
Expected Results: You are able to edit a task Start / Finish date, also able to see all three tasks
Actual Results: You will see an error message pop up here warning that “Drag and drop is disabled. Task hierarchies greater than two levels are not supported”, and some tasks are missing (only the top level hierarchy task and bottom hierarchy task is shown. Any tasks in between are not shown in the new UX)
This applies to the New UX CA PPM 15.1 and higher
The new user experience currently only supports two levels of WBS. For any projects that have more than two task WBS levels, you will only be able to partially edit tasks in the new UX and some tasks may be missing if they are not the top or bottom level tasks in the WBS structure.
Some features that are available if using more than two levels of WBS include:
Some features that are not available if using more than two levels of WBS include:
Workaround: To work with more than two levels in a project, use the Gantt in the Classic (old) UI or one of the supported scheduler tools (Open Workbench (OWB) or Microsoft Project (MSP))

Starting in 15.7, there's a new task timeline that does support more than 2 levels
