ABAP后台作业设置过程：
1.变式校验
2.当前作业是否正在运行（加锁及防重）
3.后台作业提交
1.变式校验：
SELECT SINGLE @abap_true FROM varid WHERE report = @lv_report AND variant = @lv_vart INTO @DATA(lv_exists).
2.是否正在运行：
SELECT SINGLE @abap_true FROM tbtco WHERE jobname = @lv_jobname AND status IN (@/isdfps/cl_const_abc_123=>gc_s, @/isdfps/cl_const_abc_123=>gc_r, @/isdfps/cl_const_abc_123=>gc_y) INTO @DATA(lv_true).
上面只针对jobname名称进行校验，如果对当前执行程序进程进行校验，可参考https://www.cnblogs.com/ricoo/p/13846072.html：
call 'ThWpInfo' id 'OPCODE' field lc_opcode_wp_list id 'TAB' field lt_wpinfo-*sys* id 'CPU' field lv_with_cpu.
3.作业提交：
作业提交过程中需注意并发及防重执行，尽量通过作业变式分开提交，相同作业名避免记录前后执行重复。
CONCATENATE lv_report '_'lv_vart INTO lv_jobname.
