Work Processes

Work processes execute the individual dialog steps in R/3 applications. The next two sections describe firstly the structure of a work process, and secondly the different types of work process in the R/3 System

Types of WP:

Dialog Work Process

Dialog work processes deal with requests from an active user to execute dialog steps.

Update Work Process

Update work processes execute database update requests. Update requests are part of an SAP LUW that bundle the database operations resulting from the dialog in a database LUW for processing in the background.

Background Work Process

Background work processes process programs that can be executed without user interaction (background jobs).

Enqueue Work Process

The enqueue work process administers a lock table in the shared memory area. The lock table contains the logical database locks for the R/3 System and is an important part of the SAP LUW concept. In an R/3 System, you may only have one lock table. You may therefore also only have one application server with enqueue work processes.

Spool Work Process

The spool work process passes sequential datasets to a printer or to optical archiving. Each application server may contain only one spool work process

The structure of a Work process consists of the following elements-

Screen Processor: Responsible for screen logic

ABAP Processor: Responsible for processing logic

Data Interface: Responsible for Establishing and terminating connections between the work process and the database & access to database.
