CORES 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 "Results Structure for Overhead Accounting" 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_CORES TYPE CORES.
The CORES table consists of various fields, each holding specific information or linking keys about Results Structure for Overhead Accounting data available in SAP. These include PERIO (Period), OBJNR (Object number), KWAERS (Currency at Business Event Location), OWAERS (Currency Key)... 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. .
