EAMS_PDF_DATA 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 "PDF Data for Displaying and Printing on Front-End" 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_EAMS_PDF_DATA TYPE EAMS_PDF_DATA.
The EAMS_PDF_DATA table consists of various fields, each holding specific information or linking keys about PDF Data for Displaying and Printing on Front-End data available in SAP.
