I thought that the 'Find Object Navigation' component introduced in v9.1 deserved a mention here. Finding the navigation of a given component or page is a frequent requirement for both technical and functional PeopleSoft consultants. There are a number of SQL statements available that fetches the navigation of a component (you can sample some here and here). But, there is nothing like having a utility on PIA that can be used to query the navigation of an object. This is exactly what the 'Find Object Navigation' component does. You can find this in Main Menu > Enterprise Components > Find Object Navigation. Simply key in either the component or page name and the utility will return the navigations (bread crumb as well as URL) details where the object is registered.
