Hi @Luke James,

You would create an SLA Definition against a Task or its extended tables such as Incident, Requested Item, etc, but not against a Catalog Item.

If you are referring to a specific catalog item(s), you can use the SLA definition's condition field, but if not, I would simply look at SLA Definitions that are built against the [sc_req_item], [sc_request], and [sc_task] tables.

Cheers
