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”

Once you provide the email address you will receive a verification code for the first time which you need to enter it back in the above page to complete the process. Verification field will be enabled after you provide the email address.
