Customize Approaching Deadline Notification E-mail

There is some good information here:

I believe you can accomplish this by modifying the "ApproachingDeadlineNotification*.html" template (<Windchill>/codebase/templates/workflow). Keep in mind that all workflows that send "Approaching Deadline Notification" emails will use that template, so anything you change will change for all emails of that type.

Below is the file and areas that correspond to the sections you have highlighted in your email. To add "Message", look into the getProcessVariable or getActivityVariable from the documentation link above.

Hope this gives you some direction.
