Hi All,

I got an issue like the user getting workflow mails from oracle apps even her mail address is not in the override address. When i check the override address in oracle application it was none.

Is it possible to track when it's changed to none and what all the previous mail addresses used in the override mail address.??

What happens if the override address is none?? how override address become none and what all the possibilities??

Thanks,
