Rotable parts are parts that are expensive. Rotable parts are usually repaired because it usually costs more to replace a rotable part than it does to repair one.

In Servigistics, rotable parts can be maintained in a Rotable Bank, which is a virtual pool of parts in various valuations/conditions typically owned by an OEM or operator. The parts in the bank can be used to satisfy demand by removing a part from the bank and then adding one (usually a customer return or core part) to the bank. Parts within the Rotable Bank can be repaired or overhauled; therefore, they can be maintained in various valuations by the service provider. Planners usually decide if they can fulfill the demand by parts on hand or by generating repair orders. If scrap rates within the Rotable Bank cause the total number of parts in the bank to dip below a certain number, planners can get authorization to add new parts to the bank.

Rotable parts planning lets you designate certain expensive parts with negligible scrap rates (since these parts are expensive and can almost always be repaired) as rotable parts. When you define parts as rotable, they can be planned across a group of locations rather than at each individual location. This has the effect of reducing the inventory that needs to be maintained to service these parts.
