What is a root project?

Hi ​@KariB93WI 

In Workfront, "Root Project" is the top‑level project in a project hierarchy – i.e., when you use subprojects / project‑to‑project hierarchy:

• For a subproject, Root Project = the very first (top) project in that chain.
• For a stand‑alone project with no parent/children, the root project field is typically empty or not populated, which is why you're seeing blanks.

So:

• You don't "mark" a project as a root project in the UI – Workfront calculates it automatically when projects are linked hierarchically.
• If your campaigns are just separate projects linked together by Program or Portfolio, not as subprojects, then the Root Project fields will stay empty, and your "concept development" project won't show up there automatically.
• If you want to treat a concept‑development project as the "root" for reporting, use a custom field (e.g. "Campaign Root?" = Yes/No) or a naming convention, and report/group on that instead of the Root Project fields.

In other words, Root Project is a technical field for true project hierarchies, not a general "campaign parent" flag—your idea is right conceptually, but you'll want a custom field to drive that behavior today.
