In audit report i can find how long the job or report executed.
But if any of the reports executing > specified hours ( In "current activity" we can
see "executing" status.) How to find this executing status in audit tableS. Also will audit table record of cancelled jobs /reports ? ..
I think that you can find in user guides. I had never try to track reports execution, but I have done to track data movement tasks from Cognos Data Manager executed from Cognos Connection level.
