BUCC_S_MSG_DSP 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 "Consistency checks - Message with text" 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_BUCC_S_MSG_DSP TYPE BUCC_S_MSG_DSP.
The BUCC_S_MSG_DSP table consists of various fields, each holding specific information or linking keys about Consistency checks - Message with text data available in SAP.
