Use
To improve system performance, you can specify which objects are read from the database.

You want to have an overview of the status of all orders of a particular order type. In this case, make sure that all objects except for the order header are deselected.
You want additional information on partially released or partially confirmed operations (for example, the operations status). In this case, you must also select the object "operations".
You can select the following data objects:
You can define an overall profile to specify which data objects are read from the database (see
Order Information System: Profiles In Customizing). You can also change these settings manually on the initial screen.Object Hierarchies on the Database
The objects are stored on the database in a hierarchical structure. The order header is at the top of the hierarchy, followed, by the order items, the confirmations, and so on.
When specifying which objects are read from the database, note the following:
To display a particular object, the system needs to read the actual object as well as all the objects, which are situated above that object on the data base.

You want to create a list of all the components required for a certain group of orders. To be able to display components, the system needs to read the relevant order headers, order items, operation sequences, operations and components. If you select the object "components", the system will also automatically select all other required objects.
