SAP Licenses
License administration in the operational sense means installing and maintaining the SAP license keys that keep a system running, and measuring usage for compliance. It is a small but essential Basis task with commercial consequences.
SAP licence administration is two jobs: installing and renewing the licence key in SLICENSE, tied to the hardware key, before an expiry locks the system; and periodic measurement, USMM per system for named users and engines and the License Administration Workbench to consolidate across systems for the annual declaration. Accurate user classification by licence type keeps the measurement fair.

Installing the license
An SAP system needs a valid license key to operate beyond an initial period. Administrators install and renew the license (transaction SLICENSE), which is tied to the system’s hardware key. A missing or expired license eventually locks the system, so tracking expiry is important.
License measurement (USMM/LAW)
For compliance, SAP requires periodic system measurement: USMM measures named users and engine usage in a system, and the License Administration Workbench (LAW) consolidates measurements across systems for the annual audit/declaration. Accurate user classification (by license type) is key to a fair measurement.
Why it matters
Beyond keeping the system running, measurement feeds SAP’s licensing/audit process. Mis-classified users or unmeasured engines can lead to unexpected compliance costs, so administrators keep user types accurate and measurements clean.
Cloud/subscription
In cloud/RISE, licensing shifts to subscription metrics managed differently, but on-premise systems still rely on installed keys and periodic measurement.
Common pitfalls
- Letting the license expire, the system can lock.
- Mis-classified users skewing measurement/costs.
- Ignoring USMM/LAW until the audit deadline.
