CEST0 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 "Reference Table for CE0xxxx (CO-PA Internal Structure)" 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_CEST0 TYPE CEST0.
The CEST0 table consists of various fields, each holding specific information or linking keys about Reference Table for CE0xxxx (CO-PA Internal Structure) data available in SAP. These include MANDT (Client), PALEDGER (Currency type for an operating concern), VRGAR (Record Type), VERSI (Plan version (CO-PA))... 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. .
