Hi Soumyajit,
In such cases you need to maintain the entries manually or through a file in the day time and schedule a job for /SAPAPO/TS_REALIGN_COPY when you have a window for the same. I hope already you execute certain jobs when users are not in. You can schedule this accordingly.
Or you can put a logic through a program which gives message to all active users to log-off to carry out such activity (though preferred time should be when less people are in) and log-in thereafter when once job is done. For the same you can check for different threads available.
Regards
Rahul
