Did you try going through the latest documentation here: https://docs.bmc.com/docs/display/bmcitbm81
Just FYI, you need to register separately on docs.bmc.com. You cannot use the communities user credentials for docs.
Hope this helps!
Thanks for the post.
You can connect with other community users and find useful information on ITBM product on IT Business Management [ARCHIVED] community group.
Hope this would be useful!
