It can be used to define the fields of other actual tables or to process "Auditable Enity API structure" 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_GRFN_S_API_AE TYPE GRFN_S_API_AE.
