CFX_TS_SYSTEM_MESSAGE is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "System Message" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_CFX_TS_SYSTEM_MESSAGE TYPE CFX_TS_SYSTEM_MESSAGE.
The CFX_TS_SYSTEM_MESSAGE table consists of various fields, each holding specific information or linking keys about System Message data available in SAP. These include EXPIRATION_TIME_UTC (UTC Time Stamp in Short Form (YYYYMMDDhhmmss)), DELETION_TIME_UTC (UTC Time Stamp in Short Form (YYYYMMDDhhmmss)), SENDER (User Name), LANGUAGE (2-Character SAP Language Code)...
