BUBAS_S_MSGE 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 "Message (Extented : Simple + Detlevel + probclass + Alsort)" 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_BUBAS_S_MSGE TYPE BUBAS_S_MSGE.
The BUBAS_S_MSGE table consists of various fields, each holding specific information or linking keys about Message (Extented : Simple + Detlevel + probclass + Alsort) data available in SAP. These include MSGID (Application Log: Message class, message ID), MSGTY (Application Log: Message type (A,E,W,I,S)), MSGNO (Application Log: Message number in message class), MSGV1 (Application Log: Message variable 1)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
