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.

 When you want to use a wage type in infotype 8 (Basic Pay) that valuates your amounts indirectly from the pay scale table, you use the TARIF module. The TARIF module is used for indirect evaluation of wage types. Indirect evaluation defines the actual amounts for each wage type that the employee is eligible for according to his or her Pay Scale Grouping for Allowances1. When using pay grades for basic pay wage types, you will use indirect evaluation module 58710 to retrieve pay grade level and store it into AMT field of the wage type2. References = 2, 1

Function GEN/8 is used to generate secondary wage types for partial periods. It reads the primary wage type from the input table (IT) and creates a corresponding secondary wage type with the same amount, number, and rate. The secondary wage type is then written to the input table (IT) with the same split indicator as the primary wage type. The function can generate up to 8 secondary wage types, depending on the parameter value. For example, if the parameter is 16, then the function will generate secondary wage types /801 to /816. The secondary wage types are used for proration, factoring, and valuation purposes in the payroll schema. References = US Payroll Sub-schemas explained in simple way, Payroll Schema
