BBPS_AUTH_UI 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 UI Authorization" 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_AUTH_UI TYPE BBPS_AUTH_UI.
The BBPS_AUTH_UI table consists of various fields, each holding specific information or linking keys about Structure for UI Authorization data available in SAP. These include CLIENT (Client), DOC_GUID (GUID for Auth Data), USERNAME (Username in the Personalization Table), SET_GUID (Globally Unique identifier)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
