James,
The Order to Cash scenario is a very popular SAP EM visibility process. Unfortunately it is only made available through the RDS but luckily for you we, at Reveal, have many years experience implementing this scenario for organizations such as Insight Enterprises, Indigo Books, Asics, HD Supply, and more....
Take a look at the SAP EM WIKI we put together on SCN: SAP Event Management - Supply Chain Management (SCM) - SCN Wiki
There are lots of useful links there but toward the bottom of the page is the details that you are looking for OTC:
- Configuring an End-to-End SAP EM scenario (1/3) - Scenario Description and General Config
- Configuring an End-to-End SAP EM scenario (2/3) - ECC Configuration and Development
- Configuring an End-to-End SAP EM scenario (3/3) - SCM Configuration and Development
These are very old blogs that I wrote back i 2007!!! but they are still relevant today. Let me know if you have trouble going through them or if you need any other help.
All the best
Kevin Wilson
