Applying for an SAP License 
Your installation is assigned to one SAP software product. A license is granted for exactly one SAP system based on your installation. Your contract department will provide your installation number.
You need to apply for a separate license for each system. To determine your license key, we need the following data:
Installation Number: 10-digit number assigned by SAP
E-Mail Address: Email address of the requester
System ID: System name (C11, T11, and so on)
SAP Product: Name of the SAP Product (SAP NetWeaver, APO, BW, and so on)
Product Version: Version of the operated software product
Hardware Data: operating system, licensed database system
Hardware Key: 11-digit hardware key of your server
System Type: Production, Test (see appendix: System Types)
License Type:
Standard (License key for ABAP installation and ABAP and Java installation)
J2EE Engine (for an AS Java-only installation)
Portal(for Enterprise Portal 6.0 systems with Support Package < 9 and for Enterprise Portal 5 systems)
Determine your hardware key and then request your SAP license key.
