  • Support for changing lifecycle status focused towards Business User

2) Enhanced Service Bus Capabilities

Single stack ESB capabilities via AAE

AAE with local ES Repository and Integration Directory

Increased productivity and richer connectivity on AAE

  • IDoc-and HTTP-adapters in AAE
  • Multi-mapping message split on AAE
  • XI message packaging on AAE
  • Large (binary) file-to-file transfer
  • Configurable JDBC message size limits
  • Time-out  config. per comm. channel
  • Java proxy generation in NWDS
  • Automated Transport for Schema Validation
  • Increased Integration Directory API support
  • Increased configuration capabilities

Increased standards based interoperability

  • Publish and subscribe messaging for JMS Topics
  • Support for SOAP 1.2, WS Policy 1.2, WS Trust 1.3, Java SE6
  • WS-RM based interoperability with Microsoft .NET 3.5, 4

Runtime Architecture in a Nutshell


As of 7.3 SAP NetWeaver PI supports 2 deployment options:

Full Integration Server, two stacks


– Integration Engine (IE) (messaging +connectivity)

– BPE (ccBPM)


Java :

– AEX(messaging + connectivity)

Standalone AEX: Java Stack only

– Both deployment options can be combined

– Decentralized AEX deployment is supported

New Adapters on AAE


  • New IDoc and HTTP adapter functionality available in AAE (from 7.30)
  • JCA resource adapters (like all other AAE adapters) leveraging Adapter Framework
  • Now additional scenarios can take advantage of AAE benefits (e.g. performance, distributed processing)

Java IDoc Adapter –Overview

  • Enables IDoc connectivity for “local” AAE processing (as well as “classic”)
  • Integrated with channel monitoring for administration (unavailable for ABAP-based adapters)
  • Specific IDoc Monitor for monitoring IDoc message traffic and metadata processed on AAE
  • Supports sender IDoc Packaging and IDoc flat file modules introduced in 7.1 EHP1
  • Integrated with RFC destinations in NWA (reuse connection across channels)
  • Metadata connection details can be provided in the channel (in addition to default)
  • ALEAUD support

Java HTTP Adapter –Overview

  • Quality of Service (BE, EO, and EOIO)
  • Secure communication via SSL
  • Adapter-specific message attributes (Dynamic Configuration)
  • HTTP 1.1
  • Multipart documents
  • Form submission
  • Attachments
  • System Acknowledgement (positive & negative)

Large (Binary) File-To-File Transfer

  • Improved system robustness and reliability during large data transfer
  • Enhanced capabilities to copy very large files between locations (file share, FTP)
  • Data streaming mechanism available for File/FTP adapter
  • Complete document is not stored in memory
  • Configurable byte length of transferred chunks
  • File chunks are merged on the receiver side

Publish / Subscribe Messaging via JMS Topics

  • A wider variety of options for standards based integration to leverage current IT investments
  • Support for JMS topics for the JMS sender and receiver adapter to enable pub/sub scenarios:
  • Subscribe: Once a message is published by a JMS provider for a subscribed topic, the message is fetched and processed via SAP NetWeaver PI
  • Publish: SAP NetWeaver PI allows publishing messages to a JMS provider, such as SAP’s JMS provider
  • Support for durable subscriptions only

3) Centralized Monitoring Environment

Greater visibility into the SOA landscape through a centralized monitoring environment

  • PI monitoring Good Morning page in SAP Solution Manager*
  • PI scenarios visible within SAP Solution Manager* (for documentation)
  • New / enhanced monitoring capabilities
  • Optional additional message persistence on AAE
  • Enhanced logging on AS Java

Flexible upgrade paths

  • SAP XI 3.0
  • SAP NetWeaver PI 7.0 incl. EHP 1, EHP 2
  • SAP NetWeaver PI 7.1 incl. EHP 1

SAP NetWeaver PI Dual Level Monitoring

  • Central Tools:
  • Unified information
  • High frequency snapshots
  • Isolated runtime environment
  • Preprocessed, summarized & correlated information
  • Local Tools:
  • Real-timeinformation access
  • Detail level information (incl. payload)

4) Improved Fault Tolerance

  • Lower memory consumption and performance optimization of cache refresh
  • Optimized message processing with improved cluster communication and EOIO handling
  • “Safe Mode” during startup
  • Configuration Wizard with system parameters settings

CPA Cache Refresh

  • CPA (Collaboration Profile Agreement) cache is ES Repository and Integration Directory content compiled into runtime objects
  • Refresh triggered by change lists activation in Integration Directory and ES Repository (for runtime-relevant objects like mappings, adapter metadata, etc.)
  • Optimized object loading during full cache refresh using temporary files, cache queries in memory
  • Changed CPA cache refresh update on Adapter Engine leads to less memory consumption and less communication over server nodes


5) Integration Engine Improvements

IE Messaging –Queues Balancing

  • Sometimes messages behind big messages spend much time waiting even if other queues are available to process. This behaviour usually causes disruption in EO messages order. Now there’s a logic to rebalance the queues

IE Messaging –Queues Balancing

  • Exploit all available queues
  • Prevent unnecessary wait time
  • Keep message rather ordered
  • Messages from longer queues are reassigned to other shorter queues
  • Parameters in Integration Engine (TUNING)
