Problem Analysis in Background Processing

Definition

Problem analysis is supported by background job logs that record all messages issued by programs run in the background. Some exceptions to this are the batch input messages that are recorded in the batch input log rather than in the background processing log which is available using transaction SM35. If the output of the external program is to be recorded, it depends if it is to be started synchronously or asynchronously and how the control flag is set for the program output in the job steps. In the case of an asynchronous background job, the background processing system does not wait for an external command or program to complete before starting the next job step or completing the job. Output from this program would not be captured in the job log.

Background job logs also contain job progress and status messages from the background processing system itself.

For more information, see Displaying a Job Log.

Use

A series of tools are available for analyzing and checking the background processing environment. You can "catch" a job while it is being executed with the ABAP standard cleanup. The best places to start with problems are the job log and the SAP system log. You can find the documentation for solving problems and information on using the existing under Error Search in Background Processing System.
