Which processing class determines if a wage type should be considered for factoring?

 In SAP HCM Payroll for SAP S/4HANA, processing classes determine how wage types are processed during the payroll run. Each processing class has its own specifications, with which each wage type is processed in a different way1. Specifically, processing class 10 is used to determine whether and how wage type amounts are to be reduced2. This means that if a wage type should be considered for factoring, it would be associated with processing class 10. References =
