A maintenance object represents a grouping of tables that are maintained together on the user interface. When you add a new maintenance transaction, be sure to add a maintenance object that specifies the tables that are maintained together.

Using a MO, you have access to the back-end program components as well as to the front-end UI program components created using the Maintenance Object. This Component allows you to easily identify the objects that are associated with the primary table when you are developing and maintaining custom transactions.
