Hi Anwer,
In general the standard SAP process during outage we willsuspend the the jobs with : BTCTRNS1 and later on will release with : BTCTRNS2 after the system up and running with this the jobs which are falling the outage window will be excuted upon BG work process availability .
In your case if you don't want to execute the jobs(falling outage window) after the outage ,better to list all the jobs and change the status of these jobs from Released --> scheduled.
After the outage you need to change these jobs from scheduled -> Release basoed on it's periodicity.
Note : If you havem ore jobs ,you might need more manula work .
Regards,
Srini
