The message to SAP users is clear. To remain agile and capable of innovation, we leave the core of your ERP system as it is. If you build customizations, do so outside of your core system, in other words: 'Keep the core clean'. This simplifies maintenance based on S/4HANA updates. To increase standardization even further, S/4HANA cloud is the preferred option, as SAP automatically performs the updates every quarter. <br />
You can build customizations within the core systems, should you achieve higher cost efficiency. This cannot be achieved within the standard software and you should only choose this when it creates additional value compared to your competitors. But think about this carefully, because what seems like a great advantage today may increase complexity tomorrow.
