This trace record provides information about inbound and outbound requests and responses that are processed by the CP.
If this entry is associated with an event failure (that is, the sense data is nonzero), this entry is generated whether the SSCP option is in effect or not. It is treated as an exception condition, and therefore, is traced whenever the VIT is active.
