I am wondering if there is really a central monitoring that could detect both the message flow and adapter errors.
As you know, the messages are processed in the pipeline of the Integration Engine. The first part of the pipeline processing occurs at the ABAP stack. After the technical adapters, there is a switch to the Java side.
Could a message error be detected in the RWB (Java)?
Could an adapter error (wrong parameter in the communication channel) be detected in the message monitoring at ABAP?
