SAP S/4HANA

What is Clean Core Level C?

Extensions that use internal, unreleased SAP objects; possible but at risk of breaking during upgrades.

Level C includes direct reads of SAP tables or calls to unreleased function modules and classes. These objects can change without notice in a new release. Code at this level should be monitored by ATC and prioritized for regression testing after every upgrade.
