BAPISBLIST 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 "BO SBOOK - Key Fields and Additional Information" 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_BAPISBLIST TYPE BAPISBLIST.
The BAPISBLIST table consists of various fields, each holding specific information or linking keys about BO SBOOK - Key Fields and Additional Information data available in SAP. These include CONNID (Flight Connection Number), FLDATE (Flight date), BOOKID (Booking number), CUSTOMID (Customer Number)... 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. .
