unfortunatly the databse level calculation autofill function for setting datetime and serialnumber does not work on data import scripts.
Actually, it does work. But you have to enable that option when you do the import or set up the import script. There's a check box for enabling auto-enter options that appears in a small dialog box that appears after you click the Import button.
i did all those searches after setting up the import script but ran it unandent..
great! thanx alot!
