The diagram helps explain how SAP PM is aligned with financial, controlling, and operational structures to support structured maintenance planning and execution.
By reading this diagram, you can understand how SAP PM fits into the overall SAP organizational model and how plants, maintenance units, and planner groups are logically linked.
