AM's are 2 types

1. ROOT Application Module
2. Nested Application Module

If we are attaching AM to the Main region of the page then will call as ROOT Application Module.

If we are attaching AM to child regions or nested regions then it is called as Nested AM's.

Below Figure shows what main region and what child regions in OAF Page.

VO's containing in the main menu AM can be used any where in the child regions or nested regions.

if VO's attached to Child region AM, then you can use VO's applicable to that child region.
