# Editions and Releases

> Public Edition versus Private Edition, how MDM detects your release and applies only what it knows for certain, and what differs for you.

> **Draft brief for authors.** Replace with the final text; keep the concept-page structure.

**Contains:** SAP S/4HANA Cloud Public Edition vs Private Edition (on premise); MDM detects the release of your system from its interfaces and applies only what it identified exactly, never a guess; what "system not identified yet" means (the first minutes after a destination change, a release MDM has not recorded) and what is refused meanwhile; what differs for a user: record numbers with leading zeros, longer material numbers, columns and operations per release, columns that exist only on premise.

**Related information:** `private-edition-runtime-differences`, `equipment-private-edition`.

**Source in the product repository:** `docs/sap-editions.md`, `.claude/rules/sap-editions.md` (D81–D86).
