When someone emails my service desk, the issue is automatically set to a 'service request' issue type, which starts an SLA timer.
When the agent comes to define this issue, and moves it to a 'Change' issue type, the SLA continues, even though a Change issue does not require an SLA. This is confusing for reporting, as some change requests take months to complete, and the SLA breach will grow and grow.
Is there any way of completely removing this SLA for just a single issue, or even for a specific issue type?
