Need to add extra maintenance checks (or code) to your generated table maintenance program?
When a user uses SM30 to add an entry into table, you often need to add more checks. If you were to add code inside, there is a big chance that it would be overwritten. The solution: go to table maintenance generator ( se56) => Enviroment => add event.
There you can add the event that you want your code to run on by inserting the form name.
