SAP NetWeaver Administrator (NWA) is the administration tool for the J2EE engine (http://<host>:<port>/nwa).
Process
A Process is a language element in the CPROC language and is a container of several configuration steps.
Protocol
The CTC Protocol is an HTML based advanced logging of the execution of a configuration task. It shows all relevant information (what has been executed, which parameters have been used, what exceptions occured) and is the main source for supportability.
SC
Software components (SCs) combine development components (DCs) into larger units for delivery and deployment.
Template
Synonym: Configuration Task, CPROC
TCO
TCO (Total Cost of Ownership) represents here the total costs of setting up and maintaining an SAP system.
UI Wizard
A UI Wizard (or just wizard) is a configuration step and is stored in a CWIZ file (XML). It describes a UI that can be called during configuration to get necessary input from the user.
