 In SAP HCM Payroll for SAP S/4HANA, the operation TSDIVP (Time Schedule Division Period) is used to query the average working hours per pay period for each partial period in table PARTT. This operation calculates the average working hours by dividing the total working hours by the number of pay periods. It takes into account the specific time schedule and partial periods to provide an accurate calculation.

 In SAP HCM Payroll for SAP S/4HANA, the calculation rules MULTI RAA and ADDWT * are used to process wage types. The MULTI operation multiplies two fields of the current entry of table OT and stores the result in a third field1. The ADDWT operation adds the wage type affected to an internal table1. Given the wage type 5000 with Rate = 10, Number = 0, and Amount = 13, if it only runs through the MULTI RAA and ADDWT * calculation rules, the result in the output IT would be Rate = 10, Number = 0, and Amount = 130. This is because the MULTI operation would not change the Rate or Number as they are multiplied by 0, and the ADDWT operation would not change the Amount as it is added to an internal table without any modification1. References = 1
