What does an Organization Structure in SAP define?

An Organization Structure in SAP defines the framework of company operations, which includes elements such as departments, divisions, and other organizational units. This structure is crucial for how the business processes are organized and managed within the SAP system. It serves as the backbone for financial reporting, resource allocation, and operational control.

By creating a well-defined organization structure, companies can effectively map their internal processes to the SAP modules, allowing for streamlined workflows and better data management. This setup is also essential for authorization management, as it dictates access rights and responsibilities across various parts of the organization.

The other options describe components that are not the primary focus of the organization's structure in SAP. While the layout of physical offices may influence how departments are formed, it is not a focus of SAP's organizational framework. The hierarchical representation of users pertains more to system roles and authorizations rather than organizational structure. Lastly, the interaction between different SAP modules relates to system integration and process flow rather than the organizational architecture itself. Thus, option B accurately captures the essence of what an organizational structure defines within the SAP environment.
