Here is a scenario that I have run up against. A Work Order is Opened to repair a piece of equipment. In house technicians begin the repair but then determine that they need outside assistance. In order to keep the in house work separate from the outside vendor, the initial work order needs to be closed out and a new work order is made for the outside vendor / contractor work. This keeps the classification Outside Vendor/Contractor unique to only outside work which will show up in your KPIs.
