A resource hierarchy consists of several hierarchically structured resources. One resource can be part of several different resource hierarchies. Except for the top of the hierarchy - the hierarchy root - each resource is subordinate to another resource in the resource hierarchy.

A resource hierarchy cumulates available capacity and capacity requirements in capacity planning.

Available capacities of subordinate resources in one hierarchy level are cumulated to a superior resource.

A resource hierarchy can be created for the whole plant.

You use resource hierarchies:

• Especially in rough-cut planning and medium-term planning to check available capacity and capacity requirements of a resource group without having to consider the available capacity and capacity requirements of all subordinate individual resources
• To search for resources
