SAP Background Job Scheduling



SAP Background Job Scheduling
There are two ways to define and scheduling Background jobs, which are as follows:
1. Using transaction SM36.
2. Using Job Scheduling Wizard. (For this, we need to start Transaction SM36, and then either select Goto @ Wizard version or simply use the button for Job Wizard)
Note: first approach is best option for the users having knowledge in background job scheduling, while second approach is for the users unfamiliar with SAP Background job scheduling.
Procedure:
  1.       Enter SM36 in OK Code field or we need to choose CCMS Jobs Definition.
  2.       Now we need to assign a job name to enter it in the Job Name Field
  3.       Then, we have to set Job's Priority or 'Job Class'.
              o    High Priority: Class A
              o    Medium Priority: Class B
              o    Low Priority: Class C
   4.       Then provide Target Server Field to indicate to use system load balancing.
        o    For the system to use system load balancing to automatically select the most
              efficient application server to use at the moment, so we will leave this field empty . 
        o    Enter a specific target server to use a particular application server to run the job.
   5.       We need specify email address using Spool list recipient button so that spool request
              generated by this job to be sent to somebody's email.  
   6.       Now in start condition, we can specify when to start the job and completing the  
             appropriate selections. To make job repeated or periodic, we need to check the box at the
             bottom of screen.

   7.       In this step, we define the job's steps by choosing Step, and then specify the ABAP
             program, external command, or external program to be used for each step.

   8.       Now all we have to do is to save the fully defined job to submit it to background job
             processing.
   9.       To modify, reschedule or to manipulate a job after scheduled for first time, we need to
              manage these from the Job Overview.
