Hi,

In simple terms:

CE is to develop composite applications which sit on top of existing applications and re use thier thier functionalites as services. PI includes all capabilites of XI. It provides an infrastructure to systems so that they can interact themsevel. For example PI sits between CE and Backend systems in Service Enablement layer.

Thanks

Hi,

ce And pi

CE7.1

SAP NetWeaver Composition Environment is a platform that enables building and running applications based on Service-Oriented Architecture (SOA) principles. It offers a set of capabilities for integrating new and existing services u2013 both by SAP and proprietary, into business-specific solutions. You can develop portable standard-compliant applications based on the latest Java Enterprise Edition (Java EE) 5 technologies and integrate them with existing SAP and third-party solutions using a central enterprise service registry. SAP NetWeaver CE increases development productivity by providing model-driven composition tools for creating services and user interfaces and orchestrating them into collaborative user-centric workflows.

PI 7.1

SAP Exchange Infrastructure (SAP XI) forms the basis for the integration of business processes.

SAP XI provides a technical infrastructure for XML-based message exchange to enable the integration of SAP systems with each other on the one hand, and SAP and non-SAP systems on the other.

In SAP XI, integration knowledge is shipped in the form of pre-defined integration scenarios. Furthermore, SAP XI provides a set of integrated tools for creating and managing all integration-relevant information.

PI 7.1 and CE 7.1 are complementary solutions.

Here are some quick hints:

PI 7.1

Service-enabling tool

Focused on system to system integration (EAI)

Provides and Consumes web services for integration scenarios

CE 7.1

Composition tool

Whole development environment and infrastructure

Service consumprion tools (Web Dynpro, Visual Composer, BPM)

Cal also provide web services (when you need to implement business logic in java) using CAF

The Enterprise Services Repository (ESR) can run over both environments (PI or CE).
