Hello,
We are currently on SAP R/3 7.4, SP14 EHP5 and we want to implement a business scenario where creation / change of WBS master data trigger a custom program that send a bunch of data to a third party.
This third party is an external system type Service Oriented Architecture that collect and distribute master data to opérational applications.
My problem:
How to generate the real time event each time a WBS is created within the system? 
Modelisation:
1. Creation of WBS or WBS status change
2. This business action can be seen in tables : it generate a changes in PRPS / JCDS
3. That change should trigger a program
4. That program sends data to third party through a RFC: this part is ok manually.
The purpose of real-time and having it as event trigger: the thrid party application will only receive new information.
I don't have a job that send all my data. 
Thanks by advance for your ideas on that topic,
