Sample Program:  Start at Switch to Operating Mode (JOB_CLOSE) 

* Start job when a particular SAP operation mode becomes active.
* Operation modes are defined in the Computing Center Management
* System (CCMS, transaction SRZL).
*
* Note that internally opmode jobs are handled as “start on event”
* jobs.  This means, for example, that after BP_START_DATE_EDITOR,
* TBTCSTRT-STDTTYP is set to BTC_STDT_EVENT when a user selects an
* opmode start.
