Monitoring Updates
Use
The SAP system provides the following tools for monitoring updates and fixing errors:
-
The alert monitor for immediate notification of update problems
-
Update management for checking the status of updates, and analyzing and correcting problems.
The system also sends messages automatically for certain update problems. If there is a critical database error updating is automatically stopped by the system.
Procedure
The recommended strategy for monitoring updating and responding to problems is as follows:
Initial Status Check
Use the update manager (transaction SM13) to check the following:
-
Is the update active? If not, was it deactivated by the system or by a user?
-
Have any updates been canceled (with status Error)?
-
Is there a long queue of pending updates older than 10 minutes?

Monitoring
The graphical alert monitor (transaction RZ20) automatically issues warnings about all update problems.
The alert monitor should be running all the time as a standard component on your computer desk top. (The monitor should be started in a separate session since it blocks the SAP session in which it is started).
Troubleshooting
If canceled updates (status Error) are listed on the Update Requests screen, or if update problems are reported in the alert monitor, you can determine the cause of the error using the update manager and the system log.

Restart Updating
Updating stops automatically if a fatal database error (administrator attention required) occurs.
Once you have corrected the error, you should restart updating.

Repeat the processing of canceled updates.
After any update problem, always check for canceled updates in update management (transaction SM13). Canceled updates are assigned the status Error in the list.
If you find canceled updates, repeat them. If you do not repeat an update, the data in the update is never entered into the database, and is lost. The system automatically prevents re-processing if an update cannot safely be repeated, or if the data should be entered in the SAP system in another way.
