Process Control 

Purpose

The BW background processing system supports job or process scheduling for specified times, calendar days and after specific predecessor jobs in the Administrator Workbench. It also supports event-controlled job and process scheduling. You can use event-controlled processing to trigger processes in BW.

Process Flow

The following options are available for process control or process automation:

...

       1.      You can control several interconnected processes using Process Chains. A process chain is a sequence of processes that wait in the background for an event. Some of these processes trigger a separate event that starts other processes in turn.

       2.      You can control processes in BW with events that you have determined using Tools ® CCMS ® Jobs ® Maintain events. An event is a signal to background controlling that a particular situation has arisen in the system. Background processing then starts all processes that have been waiting for this event.

You can also activate events created in this way so that they depend on the success of one process to trigger subsequent processes. The subsequent processing function allows you to do this.

       3.      In addition to controlling using individual events, you can determine Event Collectors that have to be processed before a process is triggered.

For more information about event processing, see The Event Concept and Event Processing.

Events, event collectors and process chains are only valid in the background processing system. You can only start background jobs with an event.

In BW 3.0, automatic process control has been enhanced and improved significantly with the concept of process chains. Process control using post-processing events and event collectors is not functionally enhanced but it is still supported. This likewise applies to the InfoPackage groups. We recommend that you only use process chains for schedules of connected processes that must be re-defined.
