CEC02 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 "CO-PA: Transfer for function module for char. value selectn" 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_CEC02 TYPE CEC02.
The CEC02 table consists of various fields, each holding specific information or linking keys about CO-PA: Transfer for function module for char. value selectn data available in SAP. These include LOW (CO-PA characteristic value), HIGH (CO-PA characteristic value), SETFLAG (Flag: Low field contains name of a set), ENTRY (Possible entry: Single value or interval)... 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. .
