RMPREF02_P 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 "Foreign Trade: Preference (Report RMPREF02-Pos)" 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_RMPREF02_P TYPE RMPREF02_P.
The RMPREF02_P table consists of various fields, each holding specific information or linking keys about Foreign Trade: Preference (Report RMPREF02-Pos) data available in SAP.
