VCNUMVB 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 "Table VCKUN with update indicator" 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_VCNUMVB TYPE VCNUMVB.
The VCNUMVB table consists of various fields, each holding specific information or linking keys about Table VCKUN with update indicator data available in SAP. These include MANDT (Client), CCINS (Payment cards: Card type), CCNUM (Payment cards: Card number), CCNAME (Payment cards: Name of cardholder)... 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. .
