Decoding Technical Error 57 in SAP HR

SAP HR (Human Resources) is a powerful system that automates numerous aspects of HR management. However, like any complex software, it can sometimes throw up errors that puzzle even seasoned SAP HR users. One such error is Technical Error 57, which leaves users wondering where things went wrong. In this blog, we’ll break down this error, its causes, and solutions.

What is Technical Error 57?

Technical Error 57 in SAP HR typically occurs during Time Evaluation processes. The error message usually reads: “Technical Error 57: No rule for key…”. This means that SAP’s Time Evaluation engine cannot find a suitable rule within a Personnel Calculation Rule (PCR) to process a specific Time Management-related task.

Why Does Technical Error 57 Happen?

Here are some common reasons why Technical Error 57 occurs:

• Incorrect PCR Configuration: PCRs are the backbone of Time Evaluation in SAP HR. If a PCR is misconfigured, missing key elements, or has erroneous values, it can trigger Technical Error 57.
• Data Discrepancies: Errors in employee time data, leave records, payroll areas, or employee subgroup groupings can cause the system to be unable to find an appropriate rule to process the information.
• Customization Issues: If custom PCRs or modifications to the Time Evaluation schema exist, conflicts or errors within those customizations might cause the error.

Troubleshooting Technical Error 57

1. Check the Error Log: The detailed error log provides more specific information about which PCR the error is in and what might be missing for the rule to function. Access this log via transaction code PT60 for Time Evaluation.
2. Review PCR Configurations: Meticulously examine the PCR indicated in the error log. Scrutinize it for:
   • Missing or incorrect function calls (like OUTWP, VARST, etc.)
   • PCR structure, making sure the appropriate nodes are in place
   • Logical errors within the rule’s definition
3. Analyze Data: Verify that the employee data relevant to the PCR is correct and consistent:
   • Employee Subgroup Groupings (Table V_503_ALL)
   • Payroll areas
   • Time event types
   • Leave records
4. Debugging: For complex scenarios or custom PCRs, use SAP’s debugging tools (via transaction SE38 or SE30) to step through the Time Evaluation process and identify the precise point of failure.

Solutions that Often Work

• PCR Correction: Frequently, the solution lies in adjusting the PCR itself. Correct any incorrect entries, ensure all needed elements are in place, and that the logic of the rule flows appropriately.
• Payroll Area Alignment: Double-check that the employee’s payroll area is correctly represented in the PCR.
• Use **: In Time Evaluation, the symbol ‘**’ is often used as a wildcard to accommodate variations. If it’s missing where appropriate, add it.

Remember: Resolving Technical Error 57 might require in-depth analysis and troubleshooting with an experienced SAP HR consultant, especially if customizations are involved.
