Asset in HW Database doesnt have CI aligned

[shelley0366]

Hi

We have an asset in our HW Database that currently does not have a CI assigned, therefore our service desk cannot select the device, when a user raises a ticket.

When trying to allocate the CI to the Asset, Service Now is responding with the following message 

Changing the CI Class after creation is Not allowed.

But its never had a CI for some reason assigned

Is this correct OOB functionality

Check the model category of that 'Asset' record. Then go to 'Model categories' table, open that model category and see the 'Asset class' and 'CI class' fields. Probably the value in 'Class' field of that CI record does not match the 'CI class' of the asset's model category.

The Model Category is Tacho

Under the Asset the CI is blank 

There has never been one aligned for some reason and therefore blank

You have said that you were trying to assign some CI. What is the CI class and Model ID of that CI?
