In SAP HCM Payroll for SAP S/4HANA, the function that generates time wage types on the TIP table is GWT (Generate Wage Types). This function processes the entries of table T510S (Time Wage Type Selection), which contains the wage types that can be selected and the conditions that must be met for the selection of a wage type1.

The function DAYMO (Day Grouping for Time Wage Type Selection) can use four parameters: PAR1, PAR2, PAR3, and PAR4. These parameters are used to specify the day grouping for time wage type selection, which determines how the entries of table T510S (Time Wage Type Selection) are checked for different types of days, such as working days, Sundays, and public holidays. The parameters are defined as follows:
PAR1: Day grouping for working days
PAR2: Day grouping for Sundays
PAR3: Day grouping for public holidays
PAR4: Day grouping for other days
The values of the parameters are numerical codes that correspond to the entries in table T510S. For example, if PAR1 is set to 1, then the function DAYMO will check the entries of table T510S that have the value 1 in the field Day grouping for time wage type selection. If no entry is found, then the function DAYMO will check the entries that have the value 0 in the same field. If PAR1 is set to 0, then the function DAYMO will check only the entries that have the value 0 in the field Day grouping for time wage type selection.
The function DAYMO is usually called in the subschema TC00 (Wage Type Generation: International) or TC04 (Wage Type Generation International for Time Evaluation Without Clock Times) before the function ZLIT (Cumulate Time Wage Types), which reads the time wage types from table ZL (Time Wage Types) and cumulates them according to the cumulation class and the cumulation wage type.

The following infotypes are evaluated for factoring in payroll: Actions infotype (0000), Organizational Assignment infotype (0001), and Absences infotype (2001). These infotypes are used to determine an employee's exact remuneration, the remuneration amount is multiplied by a partial period factor1. References =

The personnel calculation rules used in the subschema of XAL9 for factoring and storage are typically designed to handle specific country-related factoring and valuation scenarios. While the exact rules can vary based on the country and the specific requirements of the payroll system, generally, rules like XVAL (for valuation) and XPPF (for partial period factoring) could be involved in such processes1.
Therefore, the correct answers could be: C. XPPF D. XVAL
These rules help in calculating the correct pay for periods where employees have variable pay due to factors like absences or changes in work schedule. It's always best to refer to the specific system documentation or configuration for the precise rules used in a given scenario.

The function WPBP (Import work center and basic pay data) in SAP HR is used to transfer master data on the work center and basic pay for the payroll period to internal table WPBP.The basic pay wage types are stored in the internal table IT. If all the fields of the table WPBP are same during the entire payroll period, this table will contain one record1. The infotypes imported by function WPBP are:
Infotype 0008 (Basic Pay)
Infotype 0007 (Work Schedules)
Infotype 0001 (Organizational Assignment)
