KNTA_SCHEDULED_TASKS
This table is the primary table owned by the scheduling engine. Every scheduled task has a row in it. For example, when a report is scheduled to run at a later time, a scheduled task is inserted into this table. When the report is completed, the scheduled task is deleted. The workflow engine uses this table in a similar fashion.
