SAP Client Introduction

A client in SAP is a legal and organizational entity and is an independent unit of the SAP R/3 system. All the business data is protected here, and other clients cannot access that data as each client in R/3 has its own environment. Every client has its own master data and transaction data, including an individual chart of account details, master records, and customizing parameters.

The SAP system is divided into different clients based on the business requirements, and it is represented by a three-digit number between 000-999, such as 200, 450, etc. So, the total number of clients that can be created in an SAP system is 1000. The data can be accessed within a client and cannot be displayed or changed by any other client in the SAP system.

All the development and customizing such as configuration, function creation, etc. in SAP R/3 is performed in a client. Data from development and customizing work can be stored in individual clients or among all the clients in a system. There are two types of client data in SAP.

1. Client dependent data – This data is specific to an individual client such as number ranges, user masters, ABAP variants, or data created or updated through R/3 transactions such as company codes, distribution channels, etc.

2. Client Independent data – It can be defined as a common data shared across all the clients in a system such as data dictionary tables, views, source code, ABAP programs, data elements, menus, and screens, etc.
