I agree with Daniel. I was pretty sure that MTWEOFI was not officially supported, but I checked the Product Announcements for DP 6.2, 7.0 and 8.0, and found nothing that mentioned this. This is probably going to require an Enhancement Request
You can avoid opening a case by submitting the Enhancement Request yourself from the URL
http://support.openview.hp.com/support.jsp
This requires HP Passport to access. Click on the Self-Solve tab, in the grey shaded area on the left, you will see 'Enhancement Requests', click on 'Submit an Enhancement Request'
