WSD_BASIC_MAT_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 "Basic material data" 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_BASIC_MAT_STY TYPE WSD_BASIC_MAT_STY.
The WSD_BASIC_MAT_STY table consists of various fields, each holding specific information or linking keys about Basic material data data available in SAP.
