PAR25 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 "Item structure for SI.CO.RE list 3-Deductions" 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_PAR25 TYPE PAR25.
The PAR25 table consists of various fields, each holding specific information or linking keys about Item structure for SI.CO.RE list 3-Deductions data available in SAP.
