It is very common requirement to stop workflow notifications going out of the system, particularly from Development instances and Test instances. Oracle have given a functionality “workflow override email address” to achieve this requirement.
In Many companies this task is done by Database Administrators (DBA) but incase you need to do it yourself you follow the below steps.
Login to Oracle Apps preferably with a user who is “Workflow System Administrator”.
Navigate to “Workflow Administrator Web Applications” Responsibility
Expand “Oracle Applications Manager”
Click “Workflow Manager”
Click “Service Components”
Click “Workflow Notification Mailer”
Click “Set Override Address”
