You can make changes to a document’s basic page layout directly from a body page. FrameMaker automatically updates both the left and right master pages, and updates the layout of any body pages that use those master pages. If any of these body pages contain layout overrides, you are asked to confirm that you want to make the updates.
If your document uses another master page—for example, for the first page of the document—you must make any layout changes on that master page.
