Fundamentals of Background Processing<br />

Lesson Duration: 45 minutes<br />

Lesson Overview<br />

In this lesson, you will learn about the basics of background processing.<br />

Lesson Objectives<br />

After completing this lesson, you will be able to:<br />

• Describe the uses of background processing<br />

• Schedule and monitor jobs<br />

Hint: What is “background processing” actually? You can use this<br />

question as an introduction to the topic.<br />

Background processing should essentially separate long-running or<br />

periodic tasks from user interaction. Long-running tasks which would<br />

occupy a work process for a long time in dialog can be sequentially<br />

processed in the background without affecting the dialog performance. An<br />

important prerequisite for achieving this goal is an appropriate sizing<br />

of the system; that is, too many background work processes could end<br />

up competing with dialog work processes for shared resources (main<br />

memory, CPU).<br />

Business Example<br />

Reports to be run regularly and long-running programs are scheduled<br />

as background jobs in the <strong>SAP</strong> system. The administrator schedules<br />

background jobs and monitors the correct process of the system’s<br />

background processing.<br />
