RCPS_EQR 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 "Equipment Requirements" 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_EQR TYPE RCPS_EQR.
The RCPS_EQR table consists of various fields, each holding specific information or linking keys about Equipment Requirements data available in SAP. These include GUID (Internal Identification for PVS Objects), GUID_MAST (Internal Identification for PVS Objects), AENNR_ROOT (Change Number)... 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. .
