BBPS_STD_ACC 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 "Local Account Assignment Data (Standalone)" 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_STD_ACC TYPE BBPS_STD_ACC.
The BBPS_STD_ACC table consists of various fields, each holding specific information or linking keys about Local Account Assignment Data (Standalone) data available in SAP. These include LOG_SYS (Logical system), ACC_CAT (Account Assignment Object), VALUE (Account assignment value), VALID_FROM (Date From Which The Generic Account is Valid)...
