I am wanting to import a batch of AP invoices into Sage 500 ERP from an excel spreadsheet.

If I were to use the Import AP data function of Sage 500 ERP and select Voucher Batch as the Import Target what is the file name that I will be importing data to ? Also, how can I find the record layout and field names of that file ?

Is there more than one database file affected when this "Import AP Data" function is completed ?
