# SSCR — Developer Keys & Object Keys **SSCR (SAP Software Change Registration)** registers manual changes to SAP-delivered sources and Dictionary objects. When a developer changes SAP standard, the system demands two different keys: **[G, FAQ]** - a **developer key** — registers *a person* as a developer. Entered **once** per user. - an **object key** — authorises changing *one specific SAP object*. One key **per object**. > **Guardrail — the first question is whether you need a key at all.** > - **Most modern systems don't.** S/4HANA, BW/4HANA and AS ABAP **7.51+** do not implement SSCR (§1). > Requesting keys for those is wasted work; being *asked* for one is a **bug** with a known Note. > - **Never delete rows from `DEVACCESS` or `ADIRACCESS` by hand.** SAP states plainly it is not > responsible for these tables and ships no deletion programs. Use the SAP for Me application. **[G, FAQ]** > - **A key is bound to the installation number.** Change the installation number (some license changes, > system copies, reassignments) and every existing key stops working (§6). > - **Keys are not a security control.** They are a licensing artefact. Control development with the > system change option (SE06), client settings (SCC4) and `S_DEVELOP`/`S_TRANSPRT` authorizations (§1). > - **No mass registration exists.** Keys are generated one at a time from accurate parameters. **[G, FAQ]** Verification legend: **[V]** verified against the live service / system during authoring
