Hi Daphine,
Creating CI's or Assets manually on the fly is not ideal practice, as duplications and inconsistencies are likely to creep in to the data - due to people applying inconsistent naming standards, misreading and mistyping attributes and so on. Many of the fields become inaccessible in SDM when you flag a CI as an Asset. And once you flag a CI as an Asset you can't easily change it back if is incorrectly classified.
Getting back to your original request, a CI Class don't have an Asset or CI flag associated with it. You might be better to enter the item in an asset register and import the asset details into SDM on a regular basis (or import their identifiers and add an MDR that points to your asset register), or add a step to the process of raising a ticket that says 'raise a request for a new asset to be registered' so that it can be done in an orderly fashion, capturing all the relevant and useful details such as vendor, model, acquisition date, warranty status and so on.
Hope that helps :-)
Regards,
James
