Assets that can be reserved in Planon ProCenter are referred to as asset units. There is a wide variety of asset units that can be registered, such as a data projector, a computer, a video projector, or a company car. These are in fact portable asset units that do not belong to a fixed space. A data projector fixed to the ceiling of a space cannot be registered as an asset unit, whereas a portable data projector can. Fixed assets can be booked along with the space unit they are located in. In that case they should be registered as a facility that is linked to the space unit. For more information on facilities, see Facilities.
