CCDATA 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: Database fields relevant to both SD and FI" 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_CCDATA TYPE CCDATA.
The CCDATA table consists of various fields, each holding specific information or linking keys about Payment cards: Database fields relevant to both SD and FI data available in SAP. These include CCNUM (Payment cards: Card number), CCFOL (Payment cards: Payment card suffix), DATAB (Payment cards: Valid from), DATBI (Payment Cards: Valid To)... 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. .
