SAP S/4HANA Cloud Public Edition, Three-System Landscape
SAP warmly welcomes all SAP S/4HANA Cloud Public Edition customers currently on 2-system landscape to the 3-system landscape conversion program! The program’s objective is to convert all installed base customers currently on 2-system landscape to the latest 3-system landscape on SAP Central Business Configuration.
SAP S/4HANA Cloud Public Edition, 3-system landscape
Previous installations of SAP S/4HANA Cloud Public Edition were based on a 2-system landscape that consists of a Quality and a Production system. Note, some of these SAP S/4HANA Cloud Public Edition customers are using solution builder framework via “Manage Your Solution” app to configure their business processes.
3-system landscape is an architecture where SAP provisions 3 systems to any customer, namely a Development, Test and Production system. This separation makes it possible to have advanced development projects, enabling developer extensibility options. This landscape leverages SAP Central Business Configuration to configure business processes within SAP S/4HANA Cloud Public Edition but aims at seamless implementation of end-to-end business processes across intelligent enterprise from one central place.
Introduction SAP S/4HANA Cloud Public Edition, 3-system landscape conversion program
SAP S/4HANA Cloud Public Edition 3-system landscape conversion is a one-time technical activity delivered exclusively by SAP. It is highly recommended to treat this conversion as a mini-project.
The conversion activities are broadly divided into two categories: pre-conversion (including the conversion event) and post-conversion. SAP Activate methodology forms the foundation of this program. These phases —Prepare, Realize, Deploy, and Run— guide both pre- and post-conversion activities. The technical tasks in the pre-conversion phase are primarily handled by the SAP team, while the post-conversion responsibilities lie with the customer.
During the pre-conversion phase, customers, and their support partners (if involved) should focus on self-enablement and developing a strong understanding of the features and capabilities of SAP Central Business Configuration and 3-system landscape. It is recommended to use the SAP Activate Conversion Roadmap extensively for enablement, scoping, and planning. This roadmap is mandatory for all customers considering or undergoing conversion. A well-informed and prepared customer team is essential to ensure a smooth transition to operations once the 3-system landscape-converted landscape is handed back.
Commercial prerequisites must be addressed collaboratively by all involved stakeholders.
Following conversion, customers must execute the project plan activities that were scoped and prepared in advance. SAP’s conversion team will provide support during the initial post-conversion period. Since each customer’s setup is unique, the level of effort required for post-conversion activities will vary. SAP offers various tools and services to help minimize the workload and streamline post-conversion tasks. The 3-system landscape conversion program provides onboarding calls, walkthroughs, and information sessions for all customers involved in the process. For further details on conversion dates and opportunities, please contact your SAP Account Team or SAP contact.
