BBP_PDS_SOS_DATA 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 "Item 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_BBP_PDS_SOS_DATA TYPE BBP_PDS_SOS_DATA.
The BBP_PDS_SOS_DATA table consists of various fields, each holding specific information or linking keys about Item Data data available in SAP.
