Unit 15: Structured Troubleshooting ADM100
If unpredictable errors occur during runtime when you call an ABAP
program, a runtime error that generates a short dump can occur
(transaction ST22).
If you want to record the internal SAP system activities, such as
authorization checks, database accesses, kernel functions, and RFC calls,
use the System Trace function (transaction: ST01).
The Performance Trace(transaction ST05) allows you to record database
calls, lock management calls, and remote calls of reports and transactions
in a trace file and to display the logged measurement results as lists. The
Performance Trace also offers extensive support for a detailed analysis
of individual trace records.
Technical information about internal SAP problems is logged in developer
traces.
System Log
Events and problems are recorded locally on each application server and
displayed in the system log in the SAP system.

If you are using the UNIX operating system, you can also work with
central logging. In this case, each application server copies its local logs to
a central log. Central logging is not possible on Microsoft Windows NT
