SAP BASIS Transaction Codes Lists

Here you find SAP basis transaction codes and with functions and usage with short description.

User Overview: Display all the users who are currently logged on to the system and show the user-ids and terminal name.

Transaction code: SM04

Lock Entry List: A lock is a mechanism that prevents other users from changing the record on which you are working.

We presume that the profile parameter rdisp/gui_auto_logout has been set. This parameter defines an automatic logout of the user if there is no activity for the set number of minutes.

Transaction code: SM12

Update Records: A failed update, or an “update terminate,” is an update to the failed database. These failed updates occur when a user entry or transaction is not entered or updated in the database.

For performance reasons, the database update is done in asynchronous mode. In this mode, the user continues to work while the system takes over the update process and waits for the database update to complete. In synchronous mode, users would have to wait until the database successfully updated before they could continue to work.

System Log: The system log is the R/3 System’s log of events, errors, problems, and other system messages.

The log is important because unexpected or unknown warnings and errors could indicate a serious problem.

Transaction code: SM21 

Batch Input: This transaction shows jobs that need to be processed or started, and jobs with errors that need to be resolved.

Transaction code: SM35

Work Processes: These transactions allow users to view the status of work processes and monitor for problems. Transaction SM51 is a central transaction from which you can select the instance to monitor. SM51 starts transaction SM50 for each application server. Transaction SM50 is used for systems without application servers.

Transaction code: SM50 / SM51

Spool: The spool is the R/3 System’s output manager. Data sent to the printer is sent to the R/3 spool and then sent to the operating system to print.

Transaction code: SP01

Tune Summary: The buffer tune summary transaction displays the R/3 buffer performance statistics. It is used to tune buffer parameters of R/3 and, to a lesser degree, the R/3 database and operating system.

The buffer is important because significant buffer swapping reduces performance. Look under Swaps for red entries. Regularly check these entries to establish trends and get a feel of the buffer behavior.

Transaction code: ST02

Temse: A TemSe (Temporary Sequential) database consistency check compares data in TST01 (TemSe objects) and TST03 (TemSe data) tables. TemSe contains temporary objects such as job logs, spool requests, tests for workflow, batch input logs, and personnel administration temporary data. Report RSTS0020 performs the consistency check.

The relationship between the object and data in the TemSe may be destroyed as a result of:

  •  Restore from backups
  •  Copying databases
  •  Copying clients using improper tools
  •  Deleting clients without first deleting their objects

Transaction code: SP12
