A functional and hierarchical grouping of assets that require planned preventative maintenance. An asset group is one of three types of item groups an asset can simultaneously belong to. The other two types are purchase item group and catalog item group. The individual items in an asset group have their own descriptions and codes.

Asset groups are added and maintained by the Planon administrator in Supporting data > Item groups or in Asset Management. They can subsequently be used in Maintenance Planner > Asset filters. If you select an asset group at Asset filters and subsequently drill down to Definitions & schedules, only the activity definitions with assets belonging to that asset group are displayed in the elements list.
