API_PVRCPD 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 "API-RCP: Variants" 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_API_PVRCPD TYPE API_PVRCPD.
The API_PVRCPD table consists of various fields, each holding specific information or linking keys about API-RCP: Variants data available in SAP. These include PNGUID (Internal Number of iPPE Node), PNCNT (Internal Counter for iPPE Objects), PVGUID (Internal Number of the PVS Variant), PVCDCNT (Internal Counter for iPPE Objects)... 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. .
