At which organizational levels is the business partner master record maintained for a supplier in SAP S/4HANA?

The business partner master record for a supplier in SAP S/4HANA is maintained at the client level. This reflects the fundamental architecture of the system, where a business partner can be centrally managed and shared across multiple company codes and purchasing organizations within the same client.

When a business partner is set up at the client level, it allows for a consistent and unified representation of the supplier's data throughout the system. This means that relevant master data, such as names, addresses, and contact information, can be consistently accessed and used by different organizational units without the need for duplication, enhancing data integrity and reducing administrative efforts.

Managing business partner records at levels such as the material group, company code, or purchasing organization introduces segregation that isn’t aligned with the central approach of business partner management in SAP S/4HANA. While specific financial data or purchasing data may be maintained at the company code or purchasing organization level, general business partner information is always held at the client level for coherence and efficiency.
