Which scenarios cause factoring to occur when they happen in the middle of a pay...

 Factoring in SAP HCM Payroll for SAP S/4HANA is used when an employee did not work for the whole payroll period, then a partial remuneration is calculated during the payroll run1. Factoring is used in the following cases: To reduce payments made to an employee because he or she joins, leaves, or is absent from the company during a period. To calculate remuneration for an exact period because of substitutions, changes in basic pay, organizational reassignments, or changes in the personal work schedule1. Therefore, the scenarios that cause factoring to occur when they happen in the middle of a pay period are when an employee has a basic pay change (Option B) and when a different work schedulerule is assigned (Option D). References = 1
