RCPS_COPY_SOURCE 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 "RMS-RCP: Copy - Data on Source Object" 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_RCPS_COPY_SOURCE TYPE RCPS_COPY_SOURCE.
The RCPS_COPY_SOURCE table consists of various fields, each holding specific information or linking keys about RMS-RCP: Copy - Data on Source Object data available in SAP. These include OBJ_KIND (RMS-ATL: Object Type RMS Workbench for a Workbench Object), KEYDATE (Valid-From Date), MA_GUID (Internal Identification for PVS Objects), MA_OBJ_KIND (RMS-ATL: Object Type RMS Workbench for a Workbench Object)... 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. .
