is regeneration of maintaince view differs in 4.0 and 4.6

A new customer defined field(y_status) was added to the table(ykxrdarea). I regenerated the changes in the maintenance view by entered the table name in the transaction SE11 and choose utilities - table maintenance generator. In the table maintenance dialog, selected generated objects from the menu and clicked on change. In the change generation elements screen selected the reason for regeneration. In my case it is new field/sec.table in structure. Hit enter. The screen was regenerated in 4.6

But when I tried the same in 4.0 versions it dint reflect the changes.

Is the regeneration procedure differs in 4.0. if yes? Please let me know
