# Business Partner as a prerequisite for SAP S/4HANA

What SAP requires of customer and supplier master data in the move to SAP S/4HANA, who is responsible for it under RISE with SAP, and a governance model supported by the SNOK MDM platform.

Report · 50 pages, 16 figures · Published: October 2026 · English and Polish editions.

## Key findings

- 1Converting customer and supplier master records to Business Partner is a precondition of system conversion - SI-Check stops the process on return code 12 at the start and on 8 or above before downtime.
- 2Under RISE with SAP, CVI and pre-conversion preparation and clean-up are excluded from the SAP service (Roles and Responsibilities, July 2026).
- 3After 2030, a system on a non-HANA database can no longer be converted (SAP, 7 October 2026); a new implementation is the remaining option.

## What is inside

- Business Partner and CVI as a precondition of system conversion - the work sequence with SAP transactions and common categories of synchronisation errors

- Materials, financial data and employees as Business Partners
- A master data governance model with roles and quality measures
- The effort model with a worked example and SNOK expert estimate

## Who it is for
