It can be used to define the fields of other actual tables or to process "Document type sets" 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_CMS_STR_DOC_TYP_SET TYPE CMS_STR_DOC_TYP_SET.
