Question:
Why my customized fields from the list view pages (Project list, Idea list...) disappears? Where are those customization saved?
Answer:
These customizations are saved into CA PPM database. If they are missing, it could be due because the view has been Published. Publish a view will remove all per-user customizations for the view.
