SNC Messages on AS ABAPLocate this document in the navigation structure

The SNC layer records SNC activation in the corresponding work process log files (dev_w.).

SNC Start Messages

It logs the relevant SNC information, to include:

  • The QoP parameters and their values
  • The path and file name of the external library
  • The user or component's own SNC name

As of Release 4.5A, a message (RIQ) is also written to the system log.
