Once jobs are defined, they are stored in the SAP database in the following principal tables in the background processing system:
¡ TBTCO: The job header table (job management data)
¡ TBTCP: The job step table (individual processing steps in jobs)
¡ TBTCS: The control table for the time-driven job scheduler
¡ BTCEVTJOB: Jobs scheduled to wait for an event
Job logs are held in the TemSe (Temporary-Sequential Objects) database. TemSe is always set to hold job logs as files in your host systems.
To display or delete job logs, use either Transaction SM37 (Job Overview) or the graphical background monitor. Old job logs and the corresponding jobs are removed automatically by the ABAP program RSBTCDEL, which should be scheduled to run periodically (see Required Background Jobs).
