在SAP中建立背景作業很簡單,　３個步驟即可完成,　代碼如下:

data: g_jobname TYPE tbtcjob-jobname VALUE 'JOB_TEST',
g_jobcount TYPE tbtcjob-jobcount,
g_jobdate TYPE BTCSDATE value '20070801',
g_jobtime TYPE BTCSTIME value '123000'.

１.使用FM：JOB_OPEN建立作業

CALL FUNCTION 'JOB_OPEN'
EXPORTING
jobname = p_jobname
IMPORTING
jobcount = p_jobcount
EXCEPTIONS
cant_create_job = 1
invalid_job_data = 2
jobname_missing = 3
OTHERS = 4.

2.提交JOB要執行的程式

SUBMIT VIA JOB p_jobname NUMBER p_jobcount
AND RETURN.

3. 設置執行日期及時間，背景作業建立完成

CALL FUNCTION 'JOB_CLOSE'
EXPORTING
jobcount = p_jobcount
jobname = p_jobname
sdlstrtdt = p_date
sdlstrttm = p_time
EXCEPTIONS
cant_start_immediate = 1
invalid_startdate = 2
jobname_missing = 3
job_close_failed = 4
job_nosteps = 5
job_notex = 6
lock_failed = 7
invalid_target = 8
OTHERS = 9.
ENDIF.

這樣一個後臺執行程序就完成,　完成後可使用SAP標準程式(TCODE: SM37)對JOB進行維護處理.
