Which calculation rule determines the valuation of the wage type based on the cumulative average...

 The calculation rule X018 is used to calculate the average of the wage type based on the cumulative values stored in the AMT and NUM fields. The operation X018 divides the AMT field by the NUM field and stores the result in the RTE field. This operation is usually performed after the cumulation of the wage type values using the ADDCU operation. The X018 operation is relevant for the valuation of time wage types according to the principle of averages, which is used for payroll and leave valuation. References = Payroll Operations, Payroll Schema, SAP HCM Payroll for SAP S/4HANA, Free SAP HCM Payroll for SAP S/4HANA Certification Sample Questions and Answers, Work Schedule Rule
