The Application Hierarchy 

The Application Hierarchy displays the organization of all the applications in your R/3 system. You can use the Application Hierarchy to look at the hierarchy of SAP applications delivered with your system. Your company's application hierarchy is either created for you or, if you have the authorization, by you.

To start the application hierarchy from the Workbench initial screen, choose Overview ® Applic. hierarchy ® SAP or Customer.

The nodes in the application hierarchy are either title nodes or development nodes. Development nodes have an accompanying development class indicating there are actual objects associated with the node. Title nodes have no development class and are used to help visually organize the hierarchy.

Whenever you assign a development class to a title node, a new development node is created.

You can use the hierarchy to locate a development class when you know the application but not its class. This is useful, for example, when you are working in a team. If a programmer needs to update an old application that is new to him, he can find the application's development class by using the hierarchy.

Click on a development class to display a list of its objects.

Creating a Hierarchy

You can also use the Application Hierarchy to depict an existing application hierarchy or plan a new application hierarchy. For example, if you wanted to add a node, you would do the following:

  1. Select a node.

    2. The node you select will provide the top of your new hierarchy.

  2. Choose Application node ®Create.

    3. The system displays the Create Node dialog box.

  3. Enter a node name or a name for a development class.

The system adds a new node. If you entered a development class name, the system uses the class short text for the node title and adds the class name to the right of the node.

You can use this option to assign an existing class to a node or create a new class for a node.

Searching within an Application

You can branch directly from the application hierarchy to the Repository Information System. You use this function whenever you want to restrict your search to the objects in one or more specific applications. Example: Suppose you are looking for a particular domain used in a financial accounting application.

To branch from the Application Hierarchy to the Repository Information System:

  1. Select one or more nodes by placing the cursor on each one and choosing Select.

    2. If you select a node, all of its subordinate nodes are also selected.
    To deselect a node, double-click it.

  2. Choose Repository Infosys.

    3. The system opens the Repository Information System.

  3. Use the Repository Information System as you normally would.
