SAP NetWeaver Process Orchestration – What’s new?

Recap: SAP NetWeaver Process Orchestration

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

SAP NetWeaver Process Orchestration Support of enterprise integration patterns Providing best practices and guidelines on how to implement common integration and business requirements on SAP NetWeaver Process Orchestration

Enterprise integration patterns  Do help in solving recurring problems faced in the integration of enterprise applications  See Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions by Gregor Hohpe and Bobby Woolf

Enterprise integration patterns on Process Orchestration  Blog on SCN describing how to best implement enterprise integration patterns on PI/PO  See SAP Process Orchestration patterns on SCN © 2013 SAP AG or an SAP affiliate company. All rights reserved.

SAP NetWeaver Process Orchestration Integrated 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 © 2013 SAP AG or an SAP affiliate company. All rights reserved.

SAP NetWeaver Process Orchestration Referenced 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

Referenced Channel

Lifecycle  Create, edit, and delete channels within SAP Process Integration Designer perspective  On activation, channels get deployed on runtime  Assign/unassign channels to Integration Flows  Activation of incompatible changes is prevented, requires undeployment of Integration Flow

SAP NetWeaver Process Orchestration Migration of directory content Migrate classical PI scenarios to integrated configuration objects (ICOs)

Using the new directory content migration tool, you could considerably reduce the migration effort

 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 Orchestration Integration 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 © 2013 SAP AG or an SAP affiliate company.

Multiple interfaces for starting a process

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
