# What MDM Never Does

> The rules MDM keeps whatever happens: never sends a create, delete or operation twice, never retries an unknown outcome by itself, never guesses, never changes SAP on an upload or an edit.

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

**Contains:** never sends a create, a delete or an SAP operation twice; never retries an unknown outcome by itself; never guesses the edition or the identity; never changes SAP on an upload or a Mass Edit; never shows data of another tenant; every refusal has a code and a next step.

**Related information:** `outcome-unknown`, `concept-editions`, `concept-identity`.

**Source in the product repository:** `.claude/rules/mass-processing.md` (D42), `.claude/rules/sap-editions.md`, `CLAUDE.md` guardrails.
