Store changed data in different table

Hello All,

I have a requirement where in I want to store changed data from one Z table into another. When I make any changes to the existing data in one Z table I need to log the changes (old values) in another Z table. I have tried to check events in table maintainence generator, but do not get the old values in any event. Apart from using a module pool is there a way using events for a table maintenance where in changes/deletions can be recorded into another table(history table).

Thanks and Regards,

Sachin
