Hello Kalyan,
I know my answer won't solve this question but if it is regular that user data needs to be exported to other systems, you might want to try CUA (Central User Administration).
When CUA is used, the user data needs to be set only in one system (the "central system"), and it will be easily exported to the "child systems". I am not completely sure whether this is valid for SU01 parameters (table USR05) too, but if there are sandbox/test systems available to try the CUA solution, it worth a shot.
Best regards,
Laszlo
