EVOPD_RCNEV 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 "Structure:Progress and Milestones" 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_EVOPD_RCNEV TYPE EVOPD_RCNEV.
The EVOPD_RCNEV table consists of various fields, each holding specific information or linking keys about Structure:Progress and Milestones data available in SAP. These include MANDT (Client), OBJNR (Object number), KOKRS (Controlling Area), VERSN_EV (Progress Version)... 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. .
