Epicor iScala Blank Title 117184

Hi all. I need help from anyone who has used the payroll in Epicor iScala. I'm trying to design a crystal report for payslip to be used in iScala. I can't figure a way of getting the database fields or a way to convert the DFF file to .rpt. Currently the payslip is not printing from the dff file. All the other reports in the payroll module are printing. Please help
