COPA_PRINT_HEADER 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 Item: Header" 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_HEADER TYPE COPA_PRINT_HEADER.
The COPA_PRINT_HEADER table consists of various fields, each holding specific information or linking keys about Print Line Item: Header data available in SAP. These include BELNR_VALUE (Document number of line item in Profitability Analysis), POSNR_TEXT (Long Field Label), POSNR_VALUE (Item no. of CO-PA line item), VRGAR_TEXT (Long Field Label)...
