Identifying Sub projects from the parent project

[DMaggio]

What is the easiest way to identify that a project is a sub project of another when looking at the list view of all the projects or when writing reporting for extract? In investment portal it only shows the parent project which is great! In PROJECTS how do you identify by what fields that a project is a sub project?

Hi,
You can identify with the field parent.

I don't have a parent field in my choices? Any ideas.
