Rather than reading the payroll results in traditional way using FM’s we can process the same using Payroll reader class which was designed to use with PNP logical database. SAP recommends that not to use GET PAYROLL event.  Instead sap had provided the below PRR class i.e. Payroll Results Reader class.
