BUSDEFAULT 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 "CBP: Default Fields" 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_BUSDEFAULT TYPE BUSDEFAULT.
The BUSDEFAULT table consists of various fields, each holding specific information or linking keys about CBP: Default Fields data available in SAP. These include MC_NAME1 (Search Help Field 1 (Name 1/Last Name Upper/Lower Case)), MC_NAME2 (Search Help Field 2 (Name 2/First Name) Upper/Lower Case), LANGU (Business partner: Language), POST_CODE1 (City postal code)... 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. .
