這一節主要對后臺作業（Batch JOB）中一些平時不怎么用到的內容做一下整理，有需要對后臺作業進行控制的同行可以學習參照，比如定時批量對一部分作業進行狀態的變更，控制運行中作業的數量等等。

1、SAP后臺JOB相關系統表:TBTC*

主要的有 ：

• TBTCO - 作業狀態概述表
• TBTCP - 批作業步驟概述

2、JOB的狀態: 可以使用系統函數查看 ?BDL_READ_JOB_STATUS ?或者是自己去表?TBTCO 中查找（根據STATUS 字段判斷是否完成）。

R 活動的（運行中）

Y 就緒的

P 已調度的

S 已釋放

A 已取消（出錯終止）

F 已完成（結束）

Z Released/Susp.(無中文)

JOB運行時間：TBTCO中有開始日期開始時間和結束日期結束時間，兩者直接相減就得出JOB運行的時間。

3、JOB日志查看:系統中的日志好像是沒有存放在系統表而是文件中，可以通過函數 BP_JOBLOG_READ 獲取，傳入JOB名和JOB編號就可以獲得日志信息。

?"例如：獲取失敗日志

??DATA:lt_log?TYPE?TABLE?OF?tbtc5?WITH?HEADER?LINE.

????CALL?FUNCTION?'BP_JOBLOG_READ'
??????EXPORTING
????????client????????????????=?sy-mandt
????????jobcount??????????????=?lw_job-jobcount
????????jobname???????????????=?lw_job-jobname
??????TABLES
????????joblogtbl?????????????=?lt_log
??????EXCEPTIONS
????????cant_read_joblog??????=?1
????????jobcount_missing??????=?2
????????joblog_does_not_exist?=?3
????????joblog_is_empty???????=?4
????????joblog_name_missing???=?5
????????jobname_missing???????=?6
????????job_does_not_exist????=?7
????????OTHERS????????????????=?8.
????IF?sy-subrc?<>?0.
??????MESSAGE?ID?sy-msgid?TYPE?sy-msgty?NUMBER?sy-msgno
??????????????WITH?sy-msgv1?sy-msgv2?sy-msgv3?sy-msgv4.
????ENDIF.

4、Job狀態的更改：可以通過函數BP_JOB_MODIFY來修改。

*&---------------------------------------------------------------------* *& Form MODIFY_JOB_NAME *&---------------------------------------------------------------------* * Modify user name for job owner *----------------------------------------------------------------------* * -->P_LV_JOBNUM text * -->P_GV_JOBNAME text *----------------------------------------------------------------------* FORM modify_job_name USING p_lv_jobnump_gv_jobname.DATA: ls_jobhead TYPE tbtcjob,lt_jobstep TYPE STANDARD TABLE OF tbtcstep.CALL FUNCTION 'BP_JOB_READ'EXPORTINGjob_read_jobcount = p_lv_jobnumjob_read_jobname = p_gv_jobnamejob_read_opcode = '20'IMPORTINGjob_read_jobhead = ls_jobheadTABLESjob_read_steplist = lt_jobstepEXCEPTIONSinvalid_opcode = 1job_doesnt_exist = 2job_doesnt_have_steps = 3OTHERS = 4.IF sy-subrc <> 0.ENDIF. *** ls_jobhead-sdluname = 'BATCH_NEW'.CALL FUNCTION 'BP_JOB_MODIFY'EXPORTINGdialog = 'N'jobcount = p_lv_jobnumjobname = p_gv_jobname *** new_jobhead = ls_jobheadopcode = '18'IMPORTINGmodified_jobhead = ls_jobheadTABLESnew_steplist = lt_jobstepEXCEPTIONScant_derelease_job = 1cant_enq_job = 2cant_read_jobdata = 3cant_release_job = 4cant_set_jobstatus_in_db = 5cant_start_job_immediately = 6cant_update_jobdata = 7eventcnt_generation_error = 8invalid_dialog_type = 9invalid_new_jobdata = 10invalid_new_jobstatus = 11invalid_opcode = 12invalid_startdate = 13job_edit_failed = 14job_modify_canceled = 15job_not_modifiable_anymore = 16nothing_to_do = 17no_batch_on_target_host = 18no_batch_server_found = 19no_batch_wp_for_jobclass = 20no_modify_privilege_given = 21no_release_privilege_given = 22no_startdate_no_release = 23target_host_not_defined = 24tgt_host_chk_has_failed = 25invalid_targetgroup = 26conflicting_targets = 27OTHERS = 28.IF sy-subrc <> 0.ENDIF. ENDFORM.

上面的函數中需要注意一個參數：opcode ，下面則是這個參數的具體對照解釋。
