Creating Composite Applications 

Steps

The implementation of this scenario variant includes the following processes and steps:

...

       1.      Model your composite application using the tools for process modeling that SAP NetWeaver provides:

                            a.      Design business processes with ARIS for SAP NetWeaver.

                            b.      Implement the process flow in Guided Procedures (GP) design time.

                            c.      Create or reuse existing blocks and actions.

                            d.      Design the data model using the built-in capabilities of Borland Together UML modeling tool into the SAP NetWeaver Developer Studio.

                            e.      Model the portal navigation and workcenter aspects of the application.

For more information about this phase of the scenario variant implementation, see Developing, Configuring and Adapting Applications in the Power-User Guide.

       2.      Implement the composite application in the SAP NetWeaver Developer Studio:

                            a.      Integrate external services into the application, as described in Importing External Services.

                            b.      Create entity services to implement the data model. For more information, see Modeling Entity Services

                            c.      Implement the business logic of an application service following the instructions in Modeling Application Services

                            d.      Develop the user interfaces of the composite application, as in Implementing Web Dynpro Callable Objects.

       3.      Configure the composite application:

                            a.      Create and configure the callable objects that you need for the process, as described in Exposing Applications as Callable Objects.

                            b.      Personalize your process.

                            c.      Maintain the process authorizations.

Steps b and c are typically done by a power user. For more information, see Developing, Configuring and Adapting Applications.

                            d.      Set up the services of the application. See Services and Concepts for more information.

                            e.      Configure Web Dynpro components. See Implementing Web Dynpro Callable Objects.

                              f.      Set up portal roles and pages.

       4.      Adapt the application to fit your business purposes. You can:

                            a.      Modify the process flow.

                            b.      Adapt the building elements of the process (blocks and actions).

                            c.      Enhance the implementation of the services in the composite application.

                            d.      Improve the user interfaces by enhancing the Web Dynpro components.

                            e.      Finally, you update the portal integration of your application to leverage the enhancements you have done.
