WSD_DYNAMIC_FIELD_STY 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 "Dynamical fields used for material maintenance" 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_WSD_DYNAMIC_FIELD_STY TYPE WSD_DYNAMIC_FIELD_STY.
