In the SAP S/4HANA enterprise structure, the permitted hierarchical structure for Management Accounting involves assigning a Controlling Area to an Operating Concern (B). This structure allows for the integration of detailed cost accounting data (from the Controlling Area) with the broad, market-oriented data captured in the Operating Concern, which is used for profitability analysis (CO-PA).
Assigning a controlling area to a plant (A) is not accurate because plants are assigned to company codes, and controlling areas can encompass multiple company codes.
An operating concern being assigned to a company code (C) is not correct because the operating concern is a higher-level organizational unit that can encompass multiple company codes for profitability analysis.
An operating concern being assigned to a controlling area (D) is also incorrect because the relationship flows the other way: controlling areas are assigned to operating concerns.
