SAP C_HCMP_2311 - SAP Certified Application Associate - SAP HCM Payroll for SAP S/4HANA

 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 =

In SAP HCM Payroll for SAP S/4HANA, employees are grouped for use in personnel calculation rules (PCRs) using the customizing table V_001P_K. This table is used to set the employee subgroup grouping for personnel calculation rules regardless of its current value

 The operation ELIMI in a personnel calculation rule (PCR) is used to eliminate period indicators (split indicators) for the wage type in the current work entry. This operation prepares the way for combining the values stored in wage types which up to this point were distinct1. References =

Here's a breakdown of why these are applicable to retroactive accounting:

A. "Forced retro.accounting" data field:This field allows you to manually trigger a retroactive calculation for a specific employee. This is useful in cases where normal retroactive processes might not be sufficient.

D. Customizing changes:Changes to system configuration data that impact payroll calculations (such as tax tables, deductions, etc.) will trigger retroactive accounting to ensure past payrolls are correctly aligned with the new settings.

Why the other options are incorrect:

B. Every change to customizing data...:While some changes to customizing data are payroll-relevant, not every single change will necessarily trigger a retroactive calculation.

C. A change to master data...:A change to master data in the current period won't automatically trigger retroactive accounting. For retroactive calculations, changes to master data in previous periods are typically required.
