how to use BES to transfer data immediately between 2 EBS systems.

Is there any document clearly explaining how to use BES to transfer data immediately between 2 EBS systems.

We understand the flow:

1. Register the external system first in each by generating 'System Identifier Information.' Say for EBS1 and EBS2

http://docs.oracle.com/cd/B14117_01/workflow.101/b10284/fwkevt18.htm

2. Create a business event EBS1

3. Create a subscription to this business event and choose Agent of other system 'EBS2'

4. Create a PL/SQL code to raise the business event

5. Create a table to store the data passed from the PL/SQL code via the business event.

When an event is raised, either via the WF_EVENT.Raise API or by a message arriving on an Oracle Advanced Queue (AQ) which is registered with BES. Ideally this message should be in AGENT of EBS 2.
