RCPS_KEY_DEP_OBJ 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 "Internal + External Key of Dependent Recipe Objects" 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_KEY_DEP_OBJ TYPE RCPS_KEY_DEP_OBJ.
The RCPS_KEY_DEP_OBJ table consists of various fields, each holding specific information or linking keys about Internal + External Key of Dependent Recipe Objects data available in SAP. These include PSTNR (Item Number of a Dependent Process Element), GUID_PST (Internal Identification for PVS Objects), POPNR (Item Number of a Dependent Process Element), GUID_POP (Internal Identification for PVS 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. .
