SAP S/4HANA Error 5539: Preprocessor Filter Failure
Description
This error indicates a failure during the text preprocessing phase in SAP S/4HANA, specifically when a configured filter encounters an issue. It typically occurs when the system attempts to process text data that doesn't meet expected criteria or when the filtering mechanism itself is misconfigured.
Error Message
ERR_TEXT_PREPROCESSOR_FILTER_ERROR
Known Causes
4 known causesInvalid Text Input
The text data being processed contains unexpected characters, formats, or structures that the preprocessor filter cannot handle.
Incorrect Filter Configuration
The preprocessor filter rules or settings are not correctly configured for the type of text data being processed, leading to rejection.
Custom Filter Logic Error
Issues within custom preprocessor filter implementations are causing unexpected failures during text processing within the system.
System Environment Issue
Underlying system environment problems, such as resource constraints or temporary service interruptions, may lead to filter processing failures.
Solutions
4 solutions available1. Verify Preprocessor Configuration and Syntax medium
Ensures the preprocessor logic is correctly defined and syntactically sound.
1
Identify the specific preprocessor rule or configuration causing the error. This might involve examining system logs (e.g., SM21, ST11) for more detailed error messages related to the preprocessor. Look for keywords like 'preprocessor', 'filter', or specific function module names.
2
Access the relevant preprocessor configuration in SAP S/4HANA. The exact transaction code or configuration path can vary depending on the module or functionality using the preprocessor (e.g., for pricing, specific custom development). Common areas include custom enhancements, user exits, or Business Rule Framework plus (BRF+).
3
Carefully review the logic of the preprocessor. Check for any syntax errors, incorrect variable assignments, invalid function calls, or logical flaws. Pay close attention to data type mismatches or incorrect condition evaluations.
4
If the preprocessor is implemented using ABAP, review the ABAP code for any potential issues. Use the ABAP Development Tools (ADT) in Eclipse or the ABAP Editor (SE38) for syntax checking and debugging.
CALL FUNCTION 'MY_PREPROCESSOR_FUNCTION'
EXPORTING
input_data = lv_input
IMPORTING
output_data = lv_output
EXCEPTIONS
error_occurred = 1
OTHERS = 2.5
If BRF+ is involved, validate the decision tables, rule sets, and expressions within BRF+. Ensure all elements are correctly defined and linked.
6
Test the preprocessor logic in a development or test environment with sample data that is known to trigger the error. Use debugging tools to step through the code and understand the execution flow.
2. Check Data Consistency and Input Validity medium
Ensures the data being processed by the preprocessor is valid and consistent.
1
Identify the data that is being passed to the preprocessor when the error occurs. This often involves analyzing the transaction or process that triggers the error and examining the relevant data structures or tables.
2
Validate the integrity and completeness of the input data. Ensure all required fields are populated and that the data adheres to the expected format and data types.
3
Look for any inconsistencies or invalid values in the input data that might be causing the preprocessor to fail. For example, a date field might contain an invalid date, or a numerical field might contain non-numeric characters.
4
If the preprocessor relies on data from other SAP tables or external systems, verify the consistency and accuracy of that data as well. Use SQL queries to inspect relevant tables if necessary.
SELECT * FROM MARA WHERE MATNR = 'INVALID_MATERIAL_NUMBER';5
If the error is related to master data, ensure that the master data is correctly maintained and does not contain any corrupt or inconsistent entries. This might involve running data consistency checks within SAP.
6
Consider implementing additional data validation checks within the preprocessor logic itself to catch invalid data before it causes a failure. This can be done by adding IF statements or using specific validation function modules.

ENDIF.3. Investigate System Resources and Dependencies medium
Addresses potential issues with system performance, memory, or external dependencies.
1
Monitor system performance metrics during the execution of the process that triggers the error. Look for high CPU utilization, memory pressure, or excessive I/O. Tools like ST06, ST02, and SM50 can be useful.
2
Check for any memory allocation issues. If the preprocessor is processing large amounts of data, it might be exceeding available memory. Review SAP memory parameters (RZ11) and operating system memory settings.
3
Examine system logs (SM21, ST11) for any recurring errors or warnings that might be related to resource contention or external system failures.
4
If the preprocessor relies on external systems or services (e.g., web services, RFC destinations), verify that these dependencies are available and functioning correctly. Test the connectivity and response times of these external systems.
5
Consider the possibility of lock contention. If the preprocessor is trying to access or modify data that is locked by another process, it could lead to errors. Use SM12 to check for locks.
6
If the error occurs during peak load times, try to reproduce it during off-peak hours to determine if it's a performance-related issue.
4. Review and Apply SAP Notes easy
Checks for known issues and applies relevant SAP Notes for bug fixes.
1
Search the SAP Support Portal (support.sap.com) for SAP Notes related to error code 5539 or the error message 'ERR_TEXT_PREPROCESSOR_FILTER_ERROR'. Include keywords related to the specific SAP S/4HANA module or functionality where the error is occurring.
2
Analyze the search results for relevant SAP Notes that address similar issues or provide fixes for known bugs in the preprocessor functionality.
3
Carefully read the description and resolution of any identified SAP Notes. Pay attention to the prerequisites, affected versions, and implementation instructions.
4
If a relevant SAP Note is found, test its application in a development or test system first. Ensure that applying the note does not introduce new issues or conflicts.
5
If the SAP Note is confirmed to resolve the issue, schedule and apply it to your production system during a planned maintenance window.
