The output from the command "plist -avv PROC CASE" lists the system-defined Event code rather than action performed.

For example:

plist -avv chproc1 906

How to convert the system-defined Event code to the action performed from the verbose audit trail listing of a case

All supported operating systems

Use the audit.mes file located in the SWDIR\etc\language.lng directory or the Appendix "Understanding Audit Trails" in the TIBCO iProcess Engine Administrator’s Guide to convert the Event code to the Event description.
