You'll find the root to the answer to this one in the BMC Remedy Service Desk user guide.
You can manage configuration items even if your environment does not run BMC
Remedy Asset Management. To manage configuration items, including creating and
modifying CIs and managing inventory for bulk and non bulk CI's, you do not need
a BMC Remedy Asset management license. However, if you are running BMC
Remedy Asset Management, then you have access to additional functionality, as
described in the BMC Remedy Asset Management User's Guide. To make use of this
additional functionality, you will need either Asset Admin or User permissions and
an AR System fixed or floating license.
The license type value of "None" allows you to assign the appropriate permissions for working with CIs from the other components of the ITSM suite (such as Incident Management), without consuming an asset license. You will of course need to have an asset license for using the specific licensed Asset Management features such as the financials and contracts features - there'll be an error if unlicensed users try to work with these.
Hi, Jon -
I tested this out - set up a user with service desk access, Asset Admin/None permissions, and I was able to create a CI Unavailability record from Incident; I was also able to update and close it. I didn't try it with Asset User/None permissions.
I don't know whether that was intended to work without an Asset write license or not. Thoughts?
That's the expected behaviour in terms of licenses, yes. It's the Asset specific add-on features which need the Asset license.
