What is the purpose of table T000?

 

The table T000 in SAP is a system table that serves the purpose of storing global parameters and system-wide settings. It contains essential information about the SAP system itself. Here are some key purposes and information stored in the T000 table:

• Client-Specific Data: The T000 table contains data specific to each client in the SAP system. A client represents an organizational unit or a separate environment within the SAP system.
• System Parameters: It stores global parameters that define the behavior and configuration of the SAP system. These parameters include system-wide settings such as language, time zone, currency, calendar type, and number format.
• System Identification: The T000 table includes information about the system's identification, such as the system ID (SID) and system number. These identifiers uniquely identify the SAP system within a landscape.
• Client List: The T000 table maintains a list of all clients created in the SAP system. Each entry contains details about the client, such as client number, client name, and client-specific settings.
• System Version and Release Information: The table stores information about the SAP system's version, release level, and patch level.
• Client-Specific Authorization Data: It contains information related to client-specific authorizations, authorizations profiles, and authorizations objects.

The T000 table provides a central repository for system-wide settings and parameters, making it a critical component of the SAP system's infrastructure. It helps ensure consistent behavior across clients and enables efficient management of global settings and configurations. Modifying entries in the T000 table should be done with caution, as it directly impacts the behavior of the entire SAP system.
