SAP recently published the 15th implementation roadmap in the SAP Roadmap Viewer for "SAP S/4HANA for Central Finance". It follows the typical SAP Activate framework with the usual phases, processes and templates. Apparently, more than 100+ SAP employees with expertise from over 25 SAP projects have contributed to the know-how build-up. As normal, this roadmap can be used to implement the respective SAP solution as within a particular project.
