Operation mode Features:
When operation modes are switched, the SAP System work processes are redistributed automatically without stopping and restarting the instances. Only the work process types are changed. For example, a work process used as a dialog process can be switched for use as a background process.
The new process type is not activated until the process is free. This means that a process may not be switched immediately. Instead, a process is set to be switched when next possible. For example, if all background processes to be switched to dialog processes still have jobs, the processes are switched one by one when the jobs are completed.
Processing is not interrupted. Normal system operation continues uninterrupted during the operation mode switch.
Operation mode switches are recorded in the system log. The old process type and the new process type are recorded for each work process that is switched.
Need for exception operation mode:
Sometimes there is a requirement of more background processing from the business (say during payroll processing).
So instead of normal day operation mode, we need to set up exception operation mode.
In the system, we have already configured night operation mode which has more work process for background processing.
So while configuring exception operation mode we need to simply assign the night operation mode for the payroll period.
Detailed steps are mentioned below:
Night operation mode must be configured
Goto TCode SM63
Click on change
Now check the date and double click on 00.00-01.00 and 23.00-00.00 for setting the interval.
Note: Blue color changes to black
Now click assign and select operation mode to Night mode.
Now since we have to set the operation mode to the last day of every month click on
Day+1 button to continue for the next day and proceed same as above.
Now we can see the date as 30.06.2011
Finally, click on save.
