In Insight Builder, we are currently able to report on tasks that are in the project schedule (imported from MS Project) but we cannot report on tasks that are created in a Plan.
As an example, it can be useful to see when a specific milestone is scheduled to complete across all the projects in the organization. We can do this if the milestone is in a project schedule, but cannot do the same thing if the milestone is in a project plan.
As plan becomes a more robust tool, with new features added, we see ourselves using plan more. It would be useful to be able to draw plan information into our reports the same way we can project schedule information.
