在ABAP中，我们有时候需要通过ABAP来定义JOB并执行它，也就是说，我们不使用SM36的GUI来创建Job。
自己亲身经历的一个case：我们有一个程序performance“很差”(并不是程序的问题，而是传递给其的数据量巨大)，也就是说，我们外面有一个程序需要传递一个特别”巨大”的XML string流给该程序去解析，然而这个程序耗时也很可观，在运行时，”貌试”SAP死掉。所以，最后，solution方案就是通过一个ABAP操作Job，当然有数据的传递，使用SAP Memory.
一. JOB相关信息
例如，作为例子，我们需要一个job：去执行ZTEST_JOB_STEP1与ZTEST_JOB_STEP2这两个ABAP程序。
ZTEST_JOB_STEP1的程序：
|
REPORT ZTEST_JOB_STEP1.
PARAMETERS: p_user type sy-uname.
write:/ ‘job step 1′.
WRITE:/ ‘Proceed User:’, p_user.
|
其中效果为：带有一个variant供我们后面job用。
结果：
ZTEST_JOB_STEP2的程序：
|
REPORT ZTEST_JOB_STEP2 NO STANDARD PAGE HEADING.
write:/ ‘job step 2′.
|
其中效果为：
二. 使用ABAP操作JOB
我们的JOB-ABAP代码实现。

说明：
JOB_OPEN: 意思为：declare一个JOB并返回这个job的“内存ID”。
JOB_SUBMIT: 意思为：insert step for job。注意，这里需要为每一个step进行submit(如上面是两个program).
JOB_Close: 意思为：Release刚创建的job.然后可以在SM37中查看.
然后，我们执行：
最后结果：
然后，我们去SM37中可以check：
可以再看一下spool:
如其中ZTEST_JOB_STEP1的spool :
而ZTEST_JOB_STEP2的spool :
