SAP PI7.31/7.4

Question

Hi all
can you tel me the main difference of SAP PI 7.3.1 and 7.4?
Thanks & Regards

Answer 1

Hi Siva,
Below are my findings
  7.3 Features
Single java stack
With only having a JAVA stack it will reduce the total costs of operation:
Installation of PI7.3 with a JAVA stack only can be done within 1 hour instead of the 2 to 3 hours.
The re-start time of PI7.3 can be done in 90 seconds instead of 2 to 3 hours.
New packages can be installed within 5 minutes.
IDOC and HTTP adapters
The new version of PI the HTTP and IDOC adapter are being moved to the JAVA stack and will be called HTTP_AAE and IDOC_AAE. AAE stands for Advanced Adapter Engine.
The HTTP_AAE adapter also will be supporting a new message protocol which is the GET option, so POST and GET is possible for HTTP_AAE.
CCBPM
When moving to a Java stack only you will lose the ccBPM as this is part of the ABAP stack.
A successor of ccBPM is in development and will be called BPMN. BMPN will contain the same features as ccBPM and will be graphically presented but in another way. It gives a better overview of the interaction of the Sender and Receiver messages, it's much better presented.
Central Monitoring
Monitoring in SAP PI7.3 we will now be able to centrally monitor multiple PI domains. Central monitoring is done via Solution Manager 7.1. The mean reasons to have a central monitoring tool with Solution manger are:
Growing PI landscape complexity and distribution leads to growing requirements towards a central monitoring
Handover procedures
From incident detections to root cause
Reduce the TCO by simplification of the operations processes e.g. providing one central entry point combining monitors for PI overall status with drill-down options up to host level.
  Reduce the time for:
System checks
      Enable tight integration with:
System Monitoring and Root Cause Analysis
Alerting Infrastructure
Notification-/ Incident Management
Relieve productive systems from individual monitoring activities by a central collection of monitoring data.
     AEX (Advanced engine extended)
AAE changed to AEX. It provides connectivity capabilities of adapter engine as well as design and configuration tools (i.e. E.S.Repository and integration directory) to setup scenarios based on AAE.
AEX allows a complete stand alone, single stack installation option for net weaver pi.
Optional Message version (on error/ before routing/after mapping/validation)
Large (binary) file – file transfer.
Timeout configuration for communication channels.
Possibility of importing SQL Tables metadata.
Graphical support for RFC and JDBC lookup.
SAP PI 7.4 features
SAP NetWeaver 7.4 is optimized for SAP HANA. It enables the use of SAP HANA as the underlying database and facilitates the optimization of applications for SAP HANA. It also includes new and changed features for the Application Server ABAP, connectivity, UI technologies, Business Warehouse and security.
Abstract interfaces are now supported in BPM in PI 7.4
New installation type Process Orchestration (PRO) combining Java only PI deployment option Advanced Adapter Engine Extended (AEX) and SAP NetWeaver Business Process Management/Business Rules Management
Support for central Enterprise Services Repository (ESR) for multiple PI domains
New message-based alerting on Java
Eclipse-based tools (in NWDS) for ESR and Configuration, latter so called Integration Flows.
Logging of synchronous messages in the adapter engine
Enhancements of the Java IDoc adapter
Runtime improvement via large message queue on the adapter engine
Directory Content Migration tool to migrate classical configuration objects to Integrated Configuration (as of PI 7.3 SP9, 7.31 SP7. 7.4 SP2)
Support for parameterized mappings in Integrated Configuration and Integration Flows.
Support for extended receiver determination in Integrated Configuration and Integration Flows.
Seamless end-to-end development experience across components based on the Eclipse Development Environment including running sample scenarios provided for trial access in the Cloud, complemented by documentation, tutorials and working code.
Hope it will helpful
