Functions for the Payroll Schema: The official documentation for the WPBP function explicitly states its purpose. It reads data from the infotypes Actions (0000)
Organizational Assignment (0001)
Planned Working Time (0007)
Basic Pay (0008)
and Cost Distribution (0027) to create the work center/basic pay table. This table forms the basis for remuneration. (Accessed under SAP ERP Central Component -> Human Resources -> Payroll -> Payroll -> Tools -> Payroll Driver -> Functions for the Payroll Schema -> WPBP: Read Basic Personal Data).

Processing Steps of the Payroll Run: The documentation outlines the sequence of a payroll run. It describes that initial processing involves reading basic data (WPBP) before moving on to processing time data (like absences from IT2001) and then processing recurring and additional payments (like IT0015). This confirms the separation of duties between WPBP and other functions. (Accessed under SAP ERP Central Component -> Human Resources -> Payroll -> Payroll -> The Payroll Process -> Processing Steps of the Payroll Run).
