BUS_AS_ALL_FIELDS 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 "Business Partner: Fields of the Field Catalog (for Search)" 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_BUS_AS_ALL_FIELDS TYPE BUS_AS_ALL_FIELDS.
The BUS_AS_ALL_FIELDS table consists of various fields, each holding specific information or linking keys about Business Partner: Fields of the Field Catalog (for Search) data available in SAP. These include BP_NUMBER (Business Partner Number), MC_NAME1 (Search Help Field 1 (Name 1/Last Name)), MC_NAME2 (Search Help Field 2 (Name 2/First Name)), GUID (Business Partner GUID)...
