Users in our QA and UAT portal environements are experiencing this error -- intermittently for no apparent reason. This occurs even when the person's timesheet is not locked in the backend. We also experienced this when performing a 'playback' of LoadRunner recordings for single employees in our pre-production environment.
Enqueue traces of a single time entry session show multiple enques and dequeues. Maybe multiple user sessions are opened and they are competing for the CATS_ENQUE lock?
Certainly, we can manually delete sessions in SM04 and delete lock entries in SM12. But we need to find the root cause and implement a solution that will prevent this from happening (except when the timesheet is really locked).
Has anyone experienced this situation?
