CCDATS 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: Transaction Data - SD Database Fields" 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_CCDATS TYPE CCDATS.
The CCDATS table consists of various fields, each holding specific information or linking keys about Payment Cards: Transaction Data - SD Database Fields data available in SAP. These include CCALL (Payment cards: Status when external system is called?), REACT (Payment cards: Response to authorization checks), AUTWV (Payment cards: Amount to be authorized), CCOLD (Payment cards: Authorization has expired)... 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. .
