VPCA_MASTER 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 "Change Document Structure; Generated by RSSCD000" 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_VPCA_MASTER TYPE VPCA_MASTER.
The VPCA_MASTER table consists of various fields, each holding specific information or linking keys about Change Document Structure; Generated by RSSCD000 data available in SAP. These include CLIENT (Client), CARD_GUID (GUID of a Payment Card), VALID_TO (Date Valid to: UTC Time Stamp in Short Form YYYYMMDDhhmmss), VALID_FROM (Date Valid from: UTC Time Stamp in Short Form YYYYMMDDhhmmss)... 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. .
