Brokered: Handling Messages 

Purpose

This 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.

These integration processes are mandatory for the Business Process Management scenario.

Use of the Process

This IT process is part of the following IT scenario:

IT Scenario	Scenario Variant
Enabling Platform Interoperability	Providing Web Services Interoperability

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 process runs in the usage types AS and PI:

       1.      The sender system sends a message (AS).

       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 (AS).

Result

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