FTPRE 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: Selection fields in Preference" 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_FTPRE TYPE FTPRE.
The FTPRE table consists of various fields, each holding specific information or linking keys about Foreign Trade: Selection fields in Preference data available in SAP. These include PRENE_T (Foreign Trade: PRE: Vendor Declaration: ALV), GZOLX_T (Foreign Trade: PRE: Vendor Declaration: ALV), P_BETOL (Tolerance days purchase order), P_EULIF (Indicator 'Only dun EU vendors')... 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. .
