To check the coherence of your libraries and the editorial holes in a given edition
1.Open each and every page designated for the APM. The page must contain ads or ads placeholders, but no editorial content.
2.Right-click the APM icon in the Main toolbar, and then click Show Object Library. Fred displays the name of the library name that corresponds to the auto-detected editorial hole.
3.Double-check if that is the library required by that editorial hole.
4.Repeat these steps for other pages, designated for the APM.
