BPM, BRM and PI on a single Java instance

Java-only installation option for BPM, BRM and PI

Reliable message exchange using the XI 3.0 protocol

Call PI mappings from BPM process

Use business rules in PI

End-to-end monitoring of processes and related

messages

Handling of large messages

Advantages

Reduced development and operations cost

Improved performance

Recap: SAP NetWeaver Process Orchestration

implement common integration and business requirements onSAP NetWeaver Process Orchestration

Enterprise integration patterns

Do help in solving recurring problems faced in the

integration of enterprise applications

SAP NetWeaver Process OrchestrationIntegrated monitoring between PI and BPM

Improve TCO by monitoring

scenarios across PI and BPM

Context sensitive navigation

For a given BPM process instance,

show details of all associated PI

messages

For a given PI message, show

details of the associated BPM

process

Prerequisites

Mark the communication component

as integration-centric process

PI and BPM have to communicate

with each other using XI 3.0

message protocol



SAP NetWeaver Process OrchestrationReferenced channels in Integration Flows

Reduce TCO via re-use of channels

Inline Channels versus Referenced Channels

Inline Channels are part of Integration Flows

Referenced Channels are independent objects with

own lifecycle

Lifecycle

Create, edit, and delete channels within SAP Process

Integration Designer perspectiveOn activation, channels get deployed on runtime

Assign/unassign channels to Integration Flows

Activation of incompatible changes is prevented,

requires undeployment of Integration Flow Inline Chann

Referenced Chann



SAP NetWeaver Process OrchestrationMigration of directory content

Using the new directory content m

could considerably reduce the Migrate classical PI scenarios to

integrated configuration objects (ICOs) Supporting both Java-only and dual-stack

target systems

Source PI system as of XI 3.0 and newer

Tool runs in target system

Automatic directory objects matching and

migration checks

Renaming of objects via renaming rules Mass change support for communication

channels

SAP NetWeaver Process OrchestrationIntegration visibility

Central, end-to-end integration visibility into the correct closure of business transactions.

Measure business SLAs, such as end-to-end processing times, error ratio, volumes, etc.

Integration discovery Discover integration flows in your landscape including processing

within SAP NetWeaver PI, SAP backend system layers such as

ALE, tRFC

Message Flow Monitor in SAP Solution Manager*

Targeting IT & application support and business power users

Monitoring along integration layers of message exchange

Show relevant payload data, e.g., EDI number, order number, etc. Provide information of most common B2B related issues, e.g.,

flows with highest error ratio, overdue acknowledgements, etc.

Integration with SAP Operational Process Intelligence**

Visibility and decision-support tool targeting line of business users,

providing real-time information of operations and processes

including message exchange

Events for message sent / received / in error / cancelled

Multiple interfaces for

starting a process





• Challenges

• Several different interfaces• Order of appearance not predictable

• Mixture of cardinalities possible

(e.g. 1..1 or 1..n)

• Receiver expects aggregated message

comprising all interfaces






Multiple interfaces for starting a processStandard BPMN options

• Solution 1

• Using several start events• Assumption: Order Header contains

number of expected items




Multiple interfaces for starting a processStandard BPMN options

• Solution 2

• Using instantiating parallelevent-based gateway

• Assumption: Order Header contains

number of expected items
