To approve work logs, run a report that returns those work logs you want to approve (see Create Reports) and go to the "Work Log Details" in the structured view (see Reports: Work Log Details). In the structured view, only after expanding an issue you will be able to approve its work logs. From ictime version 5.8.1 on it is possible to approve work logs in the list view also.
You can't approve work logs in the list view if you are running ictime in a version up to 5.8.x.!
