Understanding SAP HR Clusters and Database Tables - Insights and Definitions

Can you tell me what is meant by a cluster in SAP HR?

---

A cluster in SAP HR refers to a group of servers or nodes that work together to provide high availability and scalability for SAP HR applications. These clusters help distribute workload efficiently and ensure that the system remains operational even if one or more servers fail. By using clusters, organizations can improve performance, reliability, and fault tolerance in their SAP HR environment.

Hi,

PCL1 - Database for HR work area (long text, etc).
PCL2 - Accounting Results (time, travel expenses, and payroll) (payroll results).
PCL3 - Applicant tracking data.
PCL4 - Documents, Payroll year-end Tax data (change logs, etc).

PCL1 Contains:
# B1 time events/PDC
# PC personal calendar

PCL2 Contains:
# B2 time accounting results
# RX payroll accounting results/international
# Rn payroll accounting results/country-specific (n = HR country indicator RU for US payroll result).

Thanks, Chamanoh,

I have submitted my papers and am preparing for an interview. What are the expected questions the interviewer may ask me about clusters and PCL1?

I know that clusters are a group of tables used for storage purposes in a storage medium. Could you please provide any broader definitions?

Please post any additional information you have.

Thank you.

Hi,

I am speaking about SAP HR. To delete a personnel number, go to transaction code SE38 (ABAP Editor) -> specify the program RPUDELPN -> click on execute.

Thank you.

There are a lot of internal tables in SAP HR. WPBP (Workplace & Basic Pay), RT (Results table), CRT (Cumulative Results table), BT (Bank transaction table), C0 (Cost distribution), ARRRS (Arrears table), DDNTK (Deductions not taken). Many tables are there like this.

These are all stored in the PCL2 file in IN (Indian Payroll Results) cluster. There are a lot of internal tables like this in payroll.
