Clean Core is not about prohibiting custom logic—it is about decoupling extensions so that quarterly cloud upgrades never break operational business processes.
Key-user extensibility vs on-stack developer extensions
SAP S/4HANA provides distinct tiers of extensibility. Understanding when to use low-code custom fields versus isolated ABAP cloud development environments keeps your database pristine.
Eliminating direct table modifications
Directly querying or modifying underlying standard database tables creates catastrophic upgrade dependencies. Utilizing released public APIs and CDS views ensures forward compatibility.
Continuous automated regression testing
A clean-core architecture allows organizations to implement automated testing scripts that validate core transactions within minutes whenever updates are deployed.
