Agenda

1. Introducing Composite Applications and

SAP NetWeaver Composition Environment

2. BPM with SAP NetWeaver Composition Environment

3. Exercises


Goal

Composite Applications require a change in thinking from an architects as well as from a developers point of view.

Learn how to successfully build a composite application and apply the principles to your own projects!


Definition of a Composite Application

Wikipedia: A Composite Application is an application built by

combining multiple existing functions into a new application.

Extended Definition: Composite Applications are user centric

applications supporting highly collaborative and dynamic

business processes which span beyond functional, system,

and organizational boundaries by using data and functions

provided as services by platforms and applications.

Highlights of SAP NetWeaver CE

Leading edge process and rules mgmt capabilities

SAP NetWeaver CE Highlights

Composite Designer

Central entry point for modeling and

assembling composite applications

SAP NetWeaver BPM

Business-friendly user perspective

UI generation technology

Process reporting capabilities

Support for intermediate message events

Model-based service composition &

simplification

SAP NetWeaver BRM

Embedded rules in process to drive process

agility


Central composite application perspective

Improving the developer productivity

Composite Designer: The central entry point for modeling and

assembling composite applications

Import and editing of existing

composite applications

Create new components

such as processes, UIs, rules,

simplified services, composed

services, business objects and

navigate to specialized

perspectives to edit them

View, edit, and create

relations between

components

Framework to check

consistency of relations


Business IT

Business-friendly

process modeling perspective(in SAP NetWeaver BPM)

From modeling (no coding!) to execution (no translation!)

Developer-friendly

implementation perspective(in SAP NetWeaver BPM)

Business-friendly process modeling perspective

A first step towards collaborative process design


Auto-generation of user interfaces

Making it much easier and faster to generate new UIs

Auto-generation of user interfaces (UI) out of the

process context (data objects)

for Visual Composer and Web Dynpro Java


SAP NetWeaver CE and BI from SAP

Gain Insight Within and About Processes

Provide relevant analysis within

a process instance to support decision making

Provide relevant reports about the process in

general to optimize its performance

Process

participants

Process

owner

* Note: Out-of-the box extractors available for SAP NetWeaver Business Warehouse (BW)


Intermediate message event in an asynchronous scenario

Intermediate message

events support correlation of

corresponding event

messages to running

process instances

Connectivity to SAPs local event infrastructure for

asynchronous

communication in a

business process context

Correlation condition based

on defined process context

(data objects), business

rules and functions

Support of intermediate message events

Allowing process execution in asynchronous scenarios


Service Composition & Simplification

Service Composition -

provide a single service

based on multiple backend

services

Service Simplification -

provide simplified service

based on existing backend

service

Fully integrated with other

tools of SAP NetWeaver CE

(e.g. Visual Composer, BPM)

Capability to change

service interfaces after the

service is used in modeling

with service re-import

Service Composer

Allowing service composition & simplification

Introduction to BPMN

The primary goal of BPMN is to provide a notation that is readily understandable by all business users, from the business analysts that create

the initial drafts of the processes, to the technical developers responsible for

implementing the technology that will perform those processes, and finally, to

the business people who will manage and monitor those processes. Thus,

BPMN creates a standardized bridge for the gap between the business

process design and process implementation.OMG, BPMN 1.2 Specification

!

First published in 2002

Official standard of the Object Management Group (OMG) since 2006

Current Version: BPMN 1.2, 2.0 release scheduled for 2010

Business Process Modeling Notation Sequence Flow Overview

Activity

Gateway

Event

Activity:

A step in a process

Represents work or action to be performed

Gateway:

Controlles flow branching, merging and parallel actions

Pure logic does not do the decision itself

Event:

A signal that something has happened Can start, pause and resume or interrupt and redirect

a process or activity


Business Process Modeling Notation Activities

Human

Activity

Automated

Activity

Sub-Process

Human Activity:

Activity that has to be processed by a natural person

Automated Activity:

Activity that is processed by a system

Sub-Process:

A compound (decomposable) Activity that holds a sub-

process modeled with BPMN can be shown collapsed or expanded

11


Business Process Modeling Notation Gateways

Exclusive Choice:

Only one path can be taken

Each gate has a boolean data expression

Parallel Split (also AND gateway):

Splits sequence flow in parallel streams

Event based Choice:

Only one path can be taken

Decision is based on events, not data condition

Uncontrolled Merge:

Merge exclusive alternative incoming sequence flows

to one outgoing sequence flow

Parallel Join:

Merge parallel alternative incoming sequence flows to

one outgoing sequence flow


Business Process Modeling Notation Events

Start Event:

Creates new process instance or indicates start of a sub-process

Intermediate Timer Event:

pause the sequence flow of a process or a sub-process

for/until a specific time

Intermediate Message Event:

Wait for and receive a message

Intermediate Error:

Aborts activity on error

End Event:

Ends a sequence flow in a process or a sub-process

Termination:

Stop the process or sub-process immediately

12


Business Process Modeling Notation Orchestration and Collaboration

Pool:

A Pool contains a single BPMN- Process A sequence flow is constrained in exactly one pool

A Process diagramm may contain several pools

Differentiation between active and inactive (descriptive) poolsOnly one active pool per model

A pool generally represents a logical collection of roles,

organizational units and systems

Lane:

A pool may be divided into lanes

A lane generally represents a role or an organizational unit

Orchestration:

Modeling a process flow of control in a single

internal (active) pool

Representation as sequence flow

Collaboration:

Modeling interaction between pools (not flow of

control!)

Representation as message flow


Business Process Modeling Notation

(BPMN) Artifacts

Annotation

Data Object:

An artifact that stores process context

Accessible during whole process

Annotation:

Possibility to give comments within a process model

Pure description

Data Object

Artifacts:

Besides the modeling of the process flow, BPMN allows to model artifacts that hold

additional information such as data templates that are processed within an instance of the

process or annotations to comment and explain the process.

Agenda




3. Exercises


Exercise

Phase 1: Modeling the Investment Approval Process

Build a basic composite application from scratch

Requester starts the process

Approver gets the request into his/her UWL inbox

In case of approval: an automatic step will create the

purchase order (entry on database)

In case of rejection: the requester can rework the request

and initiate the approval again

The confirmation is a visual indicator that the purchase

order was created

The business workflow is assembled by

3 generated Web Dynpro Uis

for requester approval

for rework data

for confirmation

1 modelled business object

or the purchase order on local database

14


Exercise

Execute the Investment Approval Process

2) Approve / Reject the request

1) Start the process

3) Recognize the creation confirmation


Exercise

Phase 2: enhance the process with a business rule

Add a business rule to the process

The rule checks whether the total purchase amount is

more than 100.000

Only if thats the case, a manual approval is needed, otherwise the approval is done automatically without

human interaction

Add a business rule to the process

Model the business rule logic

Make it available as a local web service

Enhance the process of phase 1 with

a new step and call the business rule

via the web service

Deploy and execute the process

15


Final Composite Application

NetWeaver Developer Studio shows all

components in its appropriate layer
