BBPS_PERS_WAUTH 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 "Structure for passing and getting data from UI" 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_BBPS_PERS_WAUTH TYPE BBPS_PERS_WAUTH.
The BBPS_PERS_WAUTH table consists of various fields, each holding specific information or linking keys about Structure for passing and getting data from UI data available in SAP. These include SET_GUID (Globally Unique identifier), DOC_GUID (GUID for Auth Data), USERNAME (Username in the Personalization Table), SECTIONS (Sections of the Document)...
