Table Maintenance thru Table Maintenance Generator

Hi All,

I have created a custom table and doing table maintenance using table maintenance generator. Now the requirement is that I have to do authority check for plant in the PAI event, when the user tries to change the existing records. And this authority check has to be done only for those records changed by the user and not for all the records displayed in table control. Now could anyone tell me how to identify the records which are changed by the user in the table control.

Thanks,

KK
