Executing Unbounded Processes 

Purpose

This IT process does not involve user actions. The system processes executable processes at runtime.

Use of the Process

This process is part of the following IT scenarios:

IT Scenario	Scenario Variant
Business Process Management	Usage and Adaptation of Predefined Content
Business Process Management	Process Automation
Enabling Enterprise Services	Service Orchestration

Prerequisites

The integration scenarios and integration processes are fully configured so that they can be executed.

Process Flow

The following IT process applies to the usage type PI:

       1.      System instantiates process.

When the system receives a start message for a process, it creates an instance of the corresponding integration process.

       2.      System correlates.

When a process is defined, semantic relations between messages are established using correlations. When a process is executed, correlations are generated in the process instance. If a received XML message satisfies one of the correlations, the system assigns this XML message to the corresponding process instance.

       3.      System executes process steps.

The system executes all steps that are specified in the definition for the process. A process step can, for example, specify details for sending and receiving specific XML messages, or use conditions to control further processing. 

Result

All steps of the process are executed and the corresponding XML messages are received, processed further if necessary, and sent.
