Handling Messages Across SAP NetWeaver and Non-SAP 

Purpose

This IT process does not involve user actions. The Integration Server processes the incoming messages from the sender application and sends them to the corresponding receiver. Message processing can include integration processes while doing this.

Use of the Process

This IT process is part of the following IT scenarios:

IT Scenario	Scenario Variants
Enabling Application-to-Application Processes	Application-to-Application Integration
Enabling Business-to-Business Processes	Business Partner Integration Using Industry Standards and Smaller Business Partner and Subsidiary Integration
Business Process Management	Combining Embedded and Unbounded Processes
Enabling Enterprise Services	Point-to-Point Service-Based Integration and Brokered Service-Based Integration
Enabling Platform Interoperability	Ensuring A2A and B2B Integration

Prerequisites

This process depends on the incoming message and the previously created configuration objects. These must be available in the Integration Directory and determine, for example, the receiver or receivers of a message.

Process Flow

The following IT process runs in PI and non-SAP systems:

...

       1.      The sender system sends a message (non-SAP).

       2.      The Integration Server receives the message (PI).

       3.      The Integration Server determines the receiver of the message (PI).

       4.      The Integration Server performs the required mapping between sender and receiver (PI).

       5.      The Integration Server sends the message (PI).

       6.      The Business Process Engine creates a process and performs the corresponding correlation (PI).

This step is only mandatory for the Business Process Management scenario.

       7.      The Business Process Engine performs the process step (PI).

This step is only mandatory for the Business Process Management scenario.

       8.      The receiver system receives the message (non-SAP).

Result

The incoming message is processed and sent to the determined receiver or receivers.
