When changing the request type of a ticket, we have noticed that the SLA does not change. For example, a user puts in a trouble ticket for a Blue screen. The issue can not be resolved so we need to get the user a new computer. The SLA for a Trouble ticket is 24 hours. The SLA for a new laptop is 2 weeks. If we change the request type to "Service Request/Replacement laptop" the SLA does not update to reflect the 2 week time frame.
