⚡ Smart Summary

Matchcode W in SAP HR is a special selection variant that reruns payroll only for employees whose master data has changed. Instead of reprocessing the entire payroll area, it targets the few changed personnel numbers, saving significant time.

  • ⚡ Purpose: Matchcode W selects only employees with master-data changes for a payroll rerun, skipping unchanged records.
  • ⏱️ Efficiency: Reprocessing 10 changed employees instead of 1,000 in the payroll area dramatically cuts runtime.
  • 📅 Selection Basis: It picks employees based on the changed date of the earliest master-data change recorded in Infotype 0003.
  • 🖥️ How to Run: Open the country payroll driver (PC00_MXX_CALC), open search help, choose variant W, and execute.
  • 🎯 Optional Filter: An additional screen can further restrict which changed employees are processed, but it can be bypassed.

What is Matchcode W in SAP HR?

Let us say you have run the Payroll for a particular month for all employees (say 1,000 employees in all) for a given payroll area. Once the payment is run, let us say there are some changes made in Master Data (basic Infotypes like 0014, 0015, 0008, etc.) for 10 employees.

Now it is imperative to re-run the payroll for these 10 employees. However, using the conventional payroll mechanism, SAP will process data for all 1,000 employees in the payroll area, which is time-consuming.

Need a way out? The answer lies in Matchcode W! When you select Matchcode W and run payroll, the system will only process the 10 employees whose data was changed, and the others will not be processed a second time, as there is no change in their data. It picks up the employees based on the changed date of the earliest master-data change in SAP Infotype 0003.

Steps to Run Matchcode W in SAP HR

Step 1) Go to the payroll driver for any country using PC00_MXX_CALC – where XX is the Molga of the country.

Step 2) At the top-right side, you will have a search help button. Click on it.

Step 3) Select Variant – W.

Step 4) An additional screen is displayed, which can be used to further restrict the selection of employees with a Master Data change (10 in our above example). This screen is optional and can be bypassed.

Step 5) Execute the payroll.

Benefits of Using Matchcode W

Matchcode W offers clear advantages when only a small number of employees need their payroll reprocessed:

  • Saves processing time: Only the employees with changed master data are reprocessed, instead of the entire payroll area.
  • Reduces system load: Skipping unchanged records lowers the load on the SAP system during payroll runs.
  • Fewer errors: Reprocessing a focused set of records reduces the risk of unintended changes to correctly paid employees.
  • Faster corrections: Last-minute master-data changes can be paid quickly without waiting for a full payroll rerun.

FAQs

AI can predict payroll run times, recommend the best selection variant, and flag records likely to fail. Combined with tools like Matchcode W, it helps schedule reruns intelligently and catch issues before the payroll is finalised.

Yes. By monitoring master-data change logs, AI can identify which personnel numbers were modified and would need a rerun. This complements Matchcode W, which already selects changed employees based on Infotype 0003.

Infotype 0003 (Payroll Status) stores payroll control data for each employee, including the earliest master-data change date. Matchcode W reads this date to decide which employees to reprocess in a payroll run.

In PC00_MXX_CALC, “XX” is the country’s Molga (Modifier for Legal Area) code – for example, 10 for the USA or 08 for Great Britain. It tells SAP which country-specific payroll driver to run.
