I'm afraid so.

>Therefore, if I have a table with LastUpdate field (in my case this field called ModiDate, but it doesn't matter), I should customise my baseform.Delete method.

I see, all my tables have this fields, well more: AddDate, ModiDate & AddModiUser, in my toughts, expcept others tell me another thing, i'll put this in my transaction routine. I have one point good cause I use all the DataEnv by code, so I can put any special property for handling wich tables are deleted.
