1. What is Personalization?
Personalization enables you to declaratively tailor the UI look-and-feel, layout or visibility of page content to suit a business need or a user preference. Using Personalization we can:

    • Tailor the order in which table columns are displayed.
    • Tailor a query result.
    • Tailor the color scheme of the UI.
    • Folder Forms
    • Do Forms Personalization

2. Can you extend every possible Application Module?
No !! Root AM cannot be extended.

3. What is rootAM?
The application module which is associated with the top-level page region (the pageLayout region) is root application module.

4. Why can’t Root AM be extended?
 
The root AM is loaded first and after that the MDS Substitutions are parsed. Hence ROOT AM gets loaded even before the time the substitutions definition from MDS layer get worked out. 

Obviously, the root AM can't substitute itself, hence it can't be extended.




5. Why Should we give retainAM=Y?

The AM should be retained whenever you are navigating away from a page and when you know that there is a possibility to come back to the page again and data is to be retained. Example : Any navigation link that opens in a new page or any navigation which has a back button to come back to the initial page.
The AM should not be retained for two independent pages, especially if they have common VOs which fetch different result sets. In such cases, retaining the AM may not remove the cache of VOs and so the result may not be as expected.



6. What is the significance of addBreadCrumb=Y

The basic intention of the breadcrumb is to let the user know of the navigation path he took to reach the current page.
