A clean S/4HANA core can still sit inside a very complicated enterprise landscape.
Organizations may reduce customizations in the ERP while leaving years of surrounding complexity untouched: aging content repositories, redundant interfaces, duplicate historical data, inconsistent retention rules, and legacy applications maintained solely for occasional access.
The core may be cleaner, but the operating model around it is not.
A complete clean-core strategy should therefore examine more than code and extensions. It should also ask:
• Which historical data still requires operational access?
• How many repositories store related business documents?
• Which interfaces exist only to support legacy applications?
• Are retention rules consistent across systems and jurisdictions?
• Can users retrieve historical information without reopening an older environment?
These decisions affect more than architecture. They influence cloud consumption, upgrade complexity, audit response, support requirements, and the long-term cost of the SAP landscape.
The goal is not to move every old dependency closer to S/4HANA. It is to determine which dependencies still serve a business purpose, and create a governed alternative for those that do not belong in the future-state environment.
Neev helps SAP organizations address the data and document landscape surrounding the ERP, supporting modernization strategies that extend beyond the technical core.
Clean core should describe the complete operating environment, not only the system at its center.
