RCJ_EVVALUE 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 "Progress Analysis: Values" 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_RCJ_EVVALUE TYPE RCJ_EVVALUE.
The RCJ_EVVALUE table consists of various fields, each holding specific information or linking keys about Progress Analysis: Values data available in SAP. These include EV_ACT_ORG1 (Budgeted cost of work performed), EV_ACT_CORR1 (Budgeted cost of work performed, adjusted)... 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. .
