Configuring SAP NetWeaver 
The ABAP and the Java stack each require a set of configuration steps. Some cross-NetWeaver configuration is also required.
Configuring SAP NetWeaver ABAP
Most configuration steps for the various components of SAP NetWeaver ABAP are contained in the SAP Customizing Implementation Guide (IMG).
To call the IMG, choose 
Tools 
Customizing IMG Execute Project 
from the SAP menu to display the SAP Reference IMG. In the SAP Reference IMG,
choose the relevant section under SAP NetWeaver. Apart from the NetWeaver section, there are sections on cross-application components and the integration of other SAP components in the top IMG structure.
You can create and delete group entries, remove instances from groups, and delete entire logon groups. For configuration task on ABAP Systems, such as configuring instances, instance profiles and operation modes, you are using the Computing Center Management System (CCMS).

Configuring SAP NetWeaver Java
The JEE Engine installation procedure provides a system that is ready to be run and used. However, you may need to configure the JEE Engine additionally to adapt the system to the needs and requirements of a particular business scenario.

Cross SAP NetWeaver Configurations
Additional configuration options may be relevant to your SAP NetWeaver implementation although they don’t apply to a specific scenario.
Adobe Document Services
Adobe document services allow SAP applications (either Java or ABAP) to take advantage of the full range of capabilities in Adobe Acrobat® Professional, Adobe Acrobat Standard, and Adobe Reader®.
More Information: See Adobe Document Services Configuration Guide
SAP Licenses
After you have installed the components, the system is equipped with a temporary license, which is valid for four weeks. During this time you have to apply for a permanent license from SAP and install it.
Note that with a SAP NetWeaver Application Server with ABAP and Java, you have to import the ABAP license.
