Summary :
When attempting to install a new license key in your J2EE engine or SAP GUI, error messages may occur if there is a mismatch between system numbers or installation numbers of the existing and new license keys. Before installation, ensure that the system or installation numbers align or opt to change them. If changing, delete all previous keys via the Visual Administrator's Licensing Adapter or SAP License Administration's 'Delete License' option, even if this temporarily disables the J2EE Engine. If maintaining existing identifiers, request the appropriate license via SAP Service Marketplace, ensuring it matches the current configuration.
