Summary :
SAP systems require a valid license key linked to a hardware key, which may change with network card alterations or operating system updates as per SAP Note 174911. To manage this in environments like Amazon AWS or high availability setups, SAP allows the configuration of hardware key generation using the 'SLIC_HW_VERSION' environment variable. Default settings use the MAC address (SLIC_HW_VERSION=1). For scenarios involving multiple network cards or virtualized servers, extended (SLIC_HW_VERSION=2) or Amazon specific algorithms (SLIC_HW_VERSION=3) can be set to ensure proper license key generation.
