What do I need to configure before I can start?
Which configuration templates can I use?
Which roles do I have to assign?

Introduction

To develop a composite application, you have to install certain features for the SAP NetWeaver Developer Studio (Developer Studio) — the design time — and the SAP Application Server Java (AS Java) — the runtime. The prerequisites mentioned in this chapter are necessary for the use case “Developing Composite Applications Using SAP NetWeaver Business Process Management”. The features and capabilities mentioned as optional belong to steps that go beyond the core steps of this use case.

Activities

1. Check Installed Developer Studio Features and Server Capabilities

Check if the following AS Java and Developer Studio features and capabilities are installed.

Feature/Capability	Description/Comment
Java EE	Consists of a Developer Studio and an AS Java capability and provides a Java EE perspective.
Web Dynpro	Provides a Developer Studio perspective Web Dynpro to develop user interfaces.
Composition Tools	Provides a Developer Studio perspective Composite Designer to create and maintain composite applications easily.
Business Process Management	Consists of the Developer Studio perspective Process Composer as BPM design time and the process server as BPM runtime.
Business Rules Management — optional	Consists of the Developer Studio perspective Rules Composer as BRM design time and the rules engine as BRM runtime.
Development Infrastructure (NWDI) with lnfrastructure Client — optional	Needed for team development with the SAP NetWeaver Development Infrastructure (NWDI).
Enterprise Services Repository (ESR) – optional	Provides a central modeling and design environment for creating, aggregating, and using Enterprise Services.

To figure out whether the Developer Studio features are installed, look for the corresponding perspective:

In the Developer Studio choose in the menu bar Window Open Perspective Other... .
The Open Perspective window is displayed. It lists all available perspectives.
Look in the list for the required perspective, for example, the Process Composer perspective for modeling processes.

Note Note

Some of the features have dependencies to other features. The feature installation of the Developer Studio provides a Select Required button which automatically detects and selects depend features.

End of the note.

For more information about how to install additional features for the Developer Studio see: Update Manager

More information about the installation of AS Java for development systems is provided in the Installation Guide (Developer Edition) for SAP NetWeaver CE on SAP Service Marketplace: http://service.sap.com/instguidesnw

2. Configure Your Development Environment

Before you can develop composite applications you need to perform the following configuration steps. Directly after installation and before manual configuration, you can run the configuration wizard and use the configuration templates to save time and manual steps. Configuration templates start wizards to set preferences on the AS Java.

To run the configuration templates use the SAP NetWeaver Administrator (NWA) and then navigate to Configuration Management Scenarios Configuration Wizard

Select the following configuration templates or if not possible because it is not the initial configuration, perform the manual steps as described in the corresponding documentation.

Configuration Template	Manual Configuration
Services Registry Destinations Creation	Configuring the Services Registry Setting Destinations to UDDI Server and Classification Service
BPM All Configuration Tasks Combined	Configuring Notification Messages Service
Connection Configuration to Central Services Registry	Configuring the Services Registry Configuring a Central Services Registry
Initial setup of functional unit SLD Note For both the Enterprise Services Repository and NWDI you need to configure the System Landscape Directory (SLD) first End of the note.	Configuring System Landscape Directory Changing the SLD Configuration Configuring Systems to Connect to the SLD
If the Enterprise Services Repository is installed: Configuration of ESR in CE	Configuring Enterprise Services Repository Additional Manual Configuration
If the SAP NetWeaver Developer Infrastructure (NWDI) is installed: Change Management Service (CMS): Create an Application Skeleton Change Management Service (CMS): Modify a Software Component	Configuring Development Infrastructure Preparing CMS

To use the process desk tools and to be able to start a process within the Universal Worklist (UWL) or to just execute tasks that are included in a process, configure the process desk including the UWL.

3. Assign Roles to Users

By assigning a role to a user, you provide the user with the authorizations or functions needed to fulfill specific tasks. You can also indirectly assign a role to a user by assigning the group to which the user belongs to the role. You can manage both user management engine (UME) roles and portal roles. Portal roles define how content is displayed in the portal. UME roles define a set of authorizations.

More information: UME Roles and Portal Roles.

In the SAP NetWeaver Administrator (NWA), choose Configuration Management Security Identity Management .

Assign the following UME roles to your user:

Note Note

You can see with the code within the role's name to which tool or component the role belongs, for example, NWA_SUPERADMIN belongs to the SAP NetWeaver Administrator (NWA), SAP_BPM_Navigation belongs to SAP NetWeaver Business Process Management (BPM).

End of the note.

UME Role	Description
NWA_SUPERADMIN	Enables the user to access the SAP NetWeaver Administrator and authorizes for all administration tasks including user management and starting processes.
SAP_BPM_Navigation SAP_BPM_SuperAdmin SAP_BPM_SuperDisplay	Enables the user to access all component of the SAP NetWeaver BPM Administrator and so allows to see all deployed processes and running instances of processes and tasks. More information: Configuring BPM Users, Authorizations and Roles
SAP_CAF_ADMIN SAP_CAF_DEVELOPER	Enables the user to work with the Composite Application Framework (CAF) administrative tools and with the Service Browser. More information: Composite Application Framework Security Guide, Authorizations section
SAP_DI_ADMINISTRATOR SAP_DI_CONFIGURATOR	Enables the user to perform DI administration tasks. More information: Configuring Development Infrastructure, Setting Up Privileges, Roles and Groups section
SAP_JAVA_WSSEC_SAML	This is a security role. More information: User Management Engine
SAP_SLD_ADMINISTRATOR	Authorizes the user for all administrative tasks in the System Landscape Directory (SLD). It includes all other permissions like SAP_SLD_Developer. More information: Configuring SLD Security Roles
SERVICES_REGISTRY_READ_WRITE	Enables the user to call Read and Write APIs in the Enterprise Services Registry. More information: Configuring the Services Registry, Authorizations section
SAP_JAVA_NWADMIN_LOCAL	A local security role, which authorizes the user to enable/disable certain elements in the UI of the Web Admin tool, as well as permissions to access the data in the managed system. More information: User Management Engine
UDDI_Admin	Authorizes the user to access all data in the Services Registry and the UDDI server. More information: Configuring the UDDI Server, Configuring the Services Registry
Only if Enterprise Services Repository is installed: SAP_XI_ADMINISTRATOR_J2EE	Enables the user to define authorizations that restrict access to design and configuration objects. This role should only be granted to a restricted number of administrators. More information: Configuring Enterprise Services Repository
Only if the SAP NetWeaver Development Infrastructure installed: SAP_DI_DEVELOPER SAP_DI_OPERATOR SAP_DTR_DEVELOPER	More information: Configuring Development Infrastructure, Setting Up Privileges, Roles and Groups section
