- A SAP instance is managed by CCMS and is used by users to login.
- A SAP system can consist of one or more instances — you can set up a SAP system with a single instance with only one CCMS or you can configure a system with two or more separate instances in client/server environment.
- We need to consider the following points to configure a SAP instance:

9.Explain the architecture of SAP system with different layers. What is the use of gateway?
Presentation layer communicates with the application server to perform all the processing. This is known as the brain of a SAP system.
An application server consists of multiple instances and communicates with the database layer of the three-tier architecture.
Bottom layer is called the database layer. This is responsible to store all the data. Database of SAP system is kept on a separate server for performance and security reason.
The Presentation layer consists of different components for ABAP (Learn from SAP ABAP training) and JAVA that enables the communication and processing of data in SAP system. The key components at Presentation layer also include Gateway. This is used to manage communication between SAP system and external systems.

Support Package: SAP support packages is a bunch of corrections, this can be used by applying transaction SPAM.

A client is used in SAP system for multiple login on a single instance. You can create multiple clients on a single instance. It also provides data security as one user with one client can’t see the data of the other user with another client and also there is no need to install the software again.

SAP system comes with the following three standard clients
000 - This is called the master client and is available when you install R/3 system.
001 - This is a copy of 000 and it comes with a test company. Generally, this client is used to create new clients.
066 - This is called the SAP Early watch. This is used for diagnostic scans and monitoring service in the SAP system.
Following are the steps to create a new client in SAP
- To create a new client in SAP system, use transaction code SCC4.
- To create a new client, enter the following details after clicking on new entries:
- Client number and name
- City
