How to read this page — Every custom ABAP object in SLB's ECC landscape has been scored against SAP's Clean Core framework.
Clean Core Level (A–D) measures how close an object is to SAP standard.
Sierra Score (0–100) is Sierra Digital's composite S/4HANA readiness score — higher is better.
Recommended Action tells the migration team what to do with each object.
LOE Band is the estimated development effort to migrate it.
