Use
When a serious error occurs in the database, the SAP System automatically deactivates the Update System (see
Automatic Update Stop in the Event of Database Problems). Serious database errors require action on the part of the database administrator. Stopping updates automatically prevents updates from being processed and then being prematurely canceled on account of the database problem. This makes it easier to clean up the Update System once the error has been eliminated.If you identify a problem that also negatively impacts updates, you can manually deactivate the Update System. For instance, if you notice that there is very little free space remaining in the database, you can stop the update before the database problem causes update errors.
The procedure for manually deactivating and reactivating updates is given below.
Update deactivation should only be used as a last resort. It suspends all user transactions in the SAP System until update reactivation.
Deactivate the update program only if 1) a problem affects the entire system, and 2) the problem causes many or all updates to cancel prematurely.
Prerequisites
If you can answer any of the following questions in the affirmative, you can manually stop the update if it has not already been automatically stopped.
Procedure
To deactivate and activate updates, you can also directly call transaction SM14, and then click the appropriate pushbutton on the initial screen.
Result
Deactivation causes all active transactions in your system to be suspended.
During this time, users cannot create updates, and can only resume their work when you reactivate the Update System.Background jobs are also automatically suspended.
If it is not necessary to restart the SAP System; users can resume their work without loss of data after update reactivation. Processing of suspended jobs can also resume.
The suspension of processing is indicated in the SAPGUI status bar on each terminal.
