Learn how to customize schemas and configure rules in SAP ERP HCM to process the time recordings of employees to derive the regular and premium (time-and-a-half and double-time) hours to be paid.
Learning Objectives

Reading this article, you will learn how to:

  • Understand and interpret contract rules using a scenario sheet
  • Implement business rules in the SAP ERP HCM system by customizing schemas
  • Identify functions of the custom schema whose rules (personnel calculation rules [PCRs]) need to be adjusted
  • Configure or customize PCRs
  • Configure the related tables required for processing the recorded time of employees (called time evaluation in SAP ERP Central Component [ECC]) to generate input to payroll. This processing is done by a set of functions (collectively called schemas in ECC), which in turn contains calculation rules (called PCRs in ECC)
Key Concept
The SAP ERP HCM time evaluation program uses a sequence of functions (called schemas) to read an employee’s master data (e.g., work hours, attendances, absences, and holidays). The program then processes the master data based on personnel calculation rules (PCRs) to generate the evaluation results in the form of various hours for payment (e.g., regular hours and overtime hours).

The SAP ERP HCM system provides a framework to process all employees’ working and non-working times, such as attendances, absences, shift substitutions, holidays, and days off, to derive the hours that are to be paid as regular, overtime, holiday pay, and shift premiums. The SAP ERP HCM standard program, called time evaluation, uses this framework to process recoded times of employees. Time evaluation executes a set of functions (collectively called schemas). The functions also sometimes call personnel calculation rules (PCRs) that have the logic for processing. Several standard functions and PCRs in the system can be customized to meet a company’s specific requirements. New functions and rules can also be defined in the system, which results in processing of recorded times as per a company’s specific requirements. New functions are rarely required, although changes or customization of PCRs are very common.

I use a sample set of business rules to demonstrate how these customizations can be implemented in the SAP ERP HCM system to meet a company’s specific requirements.
