COPA_PRINT_CHAR 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 "Print Line Items: Characteristics" 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_COPA_PRINT_CHAR TYPE COPA_PRINT_CHAR.
The COPA_PRINT_CHAR table consists of various fields, each holding specific information or linking keys about Print Line Items: Characteristics data available in SAP. These include FIELD_VALUE (CO-PA characteristic value), VALUE_TEXT (KE 60-character description in RKB1T)... 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. .
