RCPS_SERVICE 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: Service Parameters" 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_SERVICE TYPE RCPS_SERVICE.
The RCPS_SERVICE table consists of various fields, each holding specific information or linking keys about RMS-RCP: Service Parameters data available in SAP. These include FLAVOR (Character field of length 40), HANDLE (2 byte integer (signed)), CHILDCAT (Workbench Object Type), APPOBJ_TYPE (Application Object Type for iPPE)... 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. .
