Message Service (BC-CST-MS)
An independent program that lists all the servers in the SAP System.
The message server:
- Decides which server a user logs on to
- Handles communication between the application servers (not RFC/CPI-C)
such as transport a lock request to the Enqueue server or transport update requests.
An SAP System with any number of application servers has one message server.
