Automate business scenarios

and user specific processes

Span beyond functional systems

and organizational boundaries

Composed / assembled

by reusable services

Loosely coupled to platform

applications

Have an own lifecycle

5. Summary

Agenda

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

Business Process Modeling Notation –

Sequence Flow Overview

Activity

Gateway

Event

Activity:

A step in the process

Represents work or action 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

© SAP 2010 / Page 11


Orchestration and Choreography

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) pools

Only 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

Choreography:

Modeling interaction between pools (not flow of

control!)

Representation as message flow

Enhanced Purchase Order Approval

Process - Description

© SAP 2010 / Page 13

Investment Approval Process in BPMN:

One Pool:

one internal (active) pool (own

company)

Two Lanes within internal pool:

one Lane for Purchase Requester Role

one Lane for Purchase Approver Role

Two Human Activities:

Purchase Request Approval (Approver)

Rework Request Data (Requester)

Confirm PO Creation (Requester)

One data inductive (automated) Activities

Create Purchase Order

One Gateway

Exclusive choice (approval yes/no)

Two Events

5. Summary

Agenda

Assigning Services and User Interfaces

to Activities and Events

Assigning Services to Automated Activities:

Import Service Interface (WSDL) to

Project from ESR, Services Registry,

Remote Location or File System

Assign Operation to process model via

Drag and Drop or in options of

automated activity

Assigning User Interfaces to Human Activities:

Generate Tasks with additional Information

about roles and behavior

Generate and Assign User Interface to

Task

Assign Task to process model via Drag

and drop or in Options of human activity

Assigning Service Operations to Events:

Assign interface and operation to message

relevant Events (e.g. start / end)

© SAP 2010 / Page 26

Business Process Modeling Notation

(BPMN) - Artifacts

Annotation

Data Object:

An artifact that stores process context

Accssesible during whole process

Annotation:

Possibility to give comments within 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.

© SAP 2010 / Page 27

Modeling the Data Flow

Hold process relevant information in data objects:

Generate artifacts that hold business process

relevant information and data (Process Context)

given by services or human interaction

Access process context from every point of the

process

Model data flow and mappings:

Model data flows to store or read information

from data objects

Map data interfaces of activities to process

context to model data flow between activities

© SAP 2010 / Page 28

Composite Application Development

Guidelines

Use Composite Designer to guide you through the overall development process

Model process skeleton (Process Composer)

Make use of context buttons

Be guided by error markers in the diagram

Assign roles/groups to lanes

Use the assignment of roles/groups on task level in exceptional cases only!

X Don‘t assign concrete users to lanes/tasks. This is like hard coding constants in a

program.

Assign an administrator to the pool


Guidelines

Model the process context as XSD file and import it to the Process Composer

Ideally names, data types, and nesting level are identical

Generate UIs (Web Dynpro or Visual Composer) based on data of process context

Ensures smooth integration between your process and the UIs


Guidelines

Automated activities: make use of the Composite Designer to create relations between

your process and other composite artifacts (e.g. CAF, Service Composer…)

Map data of each automated/human activity to the process context and vice versa

Define the conditions for every gate of a gateway

One gate needs to be the Default Gate

NOT recommended: Adding a ruleset to a gateway

X Reason: hides important information to the reader

of the process diagram!

Solution: model automated activity calling the ruleset

followed by a gateway evaluating the return value of

the automated activity!

A gateway represents logic, no activity!

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


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 stream

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


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
