CCAUT 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 "Payment Cards: Interface for 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_CCAUT TYPE CCAUT.
The CCAUT table consists of various fields, each holding specific information or linking keys about Payment Cards: Interface for Authorization data available in SAP. These include VBELN (Sales Document), FPLTR (Item for billing plan/invoice plan/payment cards), CCINS (Payment cards: Card type), CCNUM (Payment cards: Card 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. .
