I found the following article online:
http://www.novell.com/coolsolutions/feature/16583.html
that describes how to import custom reports (which I have done with no
problem).

How do I export the custom reports that I have created in Asset
Manager so that I may share them? I can't figure out how to make the .xml
file using the web console and I haven't found it in the management
console either. Thanks for your help.
