General Introduction
SAP S/4HANA is SAP’s next-generation business suite. It is not the legal successor of any SAP Business Suite product. SAP S/4HANA is a new product completely built on SAP HANA, which is one of the most advanced in-memory platforms today. In addition, SAP S/4HANA reflects modern design principles based on the SAP Fiori user experience.
In an approach to build SAP S/4HANA, SAP has re-imagined solutions for modern business processes in an increasingly mobile and digitized world. SAP S/4HANA delivers massive simplifications and innovations, deliverable on one data structure and architecture moving forward.
Converting a typical SAP ERP 6.x system to SAP S/4HANA requires a database migration to SAP HANA (if not currently running on SAP HANA), and the installation of new simplified code and adaptions.
A comprehensive overview of all simplifications for SAP S/4HANA, compared to SAP Business Suite products, are captured in the simplification list at https://help.sap.com/viewer/p/SAP_S4HANA_ON-PREMISE. For a given customer, only a limited number of simplification items from this extensive list are applicable.
To provide customers a better view of the results for their system landscapes when converting to SAP S/4HANA, SAP offers SAP Readiness Check for SAP S/4HANA.
Disclaimer
SAP does not guarantee the completeness of SAP Readiness Check for SAP S/4HANA. The readiness check is designed as a first check in system conversion planning.
The simplification list for SAP S/4HANA and its related restrictions continue to evolve, meaning some restrictions may be temporary. Also, a customer may expand the solution. The readiness check’s results reflect a specific point in time for the system in scope.
While a customer might not use some installed functions, the SAP Readiness Check for SAP S/4HANA does not in every case differentiate between used and installed components.
SAP recommends that customers carefully read the simplification list’s introduction on https://help.sap.com/viewer/p/SAP_S4HANA_ON-PREMISE. The introduction contains important information on how to interpret the simplification items.
SAP also recommends that customers always check the latest release restriction notes which might contain additional restrictions not maintained in the simplification list.
SAP Readiness Check for SAP S/4HANA’s custom code analysis identifies mandatory change areas due to the simplified application architecture of SAP S/4HANA. Custom code analysis does not contain a list of all adaptations necessary to support SAP HANA as a database. In addition, the analysis does not include general prerequisite adaptations for SAP HANA database migration. Lastly, the analysis does not include requisite adaptations for future add-ons or for custom code unrelated to SAP S/4HANA.
How Does the SAP Readiness Check for SAP S/4HANA Support You?
SAP Readiness Check for SAP S/4HANA supports customers who plan to convert existing SAP ERP 6.x systems to SAP S/4HANA. It checks both your production systems (or copies thereof) and your development systems for SAP S/4HANA conversion compatibility and necessary conversion preparation steps. The results are consolidated in an interactive dashboard for internal or for SAP communication.
SAP Readiness Check for SAP S/4HANA provides a pre-conversion overview, useful for identifying current system landscape preparation steps, well in advance of your SAP S/4HANA system conversion project start date.
