BUS_JOEL_SET 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 "Screen Structure for Joels User Settings" 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_JOEL_SET TYPE BUS_JOEL_SET.
