SAP S/4HANA Error 5536: Invalid Document Preprocessor Input
Description
This error indicates that a text preprocessor within SAP S/4HANA received an input document that does not meet its expected format, structure, or content requirements. It typically occurs when data is imported or processed from an external source or another SAP module, preventing the preprocessor from parsing the information correctly.
Error Message
ERR_TEXT_PREPROCESSOR_INVALID_INPUT_DOCUMENT
Known Causes
4 known causesIncorrect Document Format or Encoding
The input document's file type, encoding (e.g., UTF-8, ANSI), or overall structure does not align with what the SAP preprocessor is configured to accept.
Corrupted or Incomplete Input File
The document intended for processing is damaged, partially missing, or contains unreadable characters, preventing successful parsing by the preprocessor.
Malformed Content or Missing Data
Even if the file format is correct, the document's internal content might be invalid or lack essential data fields required by the preprocessor's logic.
Source System Export Error
The document originated from another system or module that generated it incorrectly, leading to an invalid output for SAP S/4HANA processing.
Solutions
3 solutions available1. Validate Document Structure and Content medium
Ensures the input document adheres to the expected format and contains valid data.
1
Identify the specific document and the preprocessor being used. This information is usually available in the application logs or the error context.
2
Refer to the documentation for the relevant SAP S/4HANA module and the specific preprocessor to understand the expected document structure (e.g., XML schema, CSV format, JSON structure).
3
Examine the input document for any structural inconsistencies, missing required fields, incorrect data types, or invalid characters. Pay close attention to character encoding, delimiters, and tag nesting if applicable.
4
If the document is generated by an external system or user, verify the output of that system or the user's input for adherence to the defined format.
5
Correct any identified structural or content errors in the input document. For example, if a required field is missing, add it. If a value has an incorrect data type, correct it.
6
Re-submit the corrected document to the SAP S/4HANA system.
2. Review Preprocessor Configuration Settings medium
Checks and adjusts the settings of the document preprocessor for correct operation.
1
Navigate to the relevant transaction code or Fiori app for configuring document preprocessors within SAP S/4HANA. This might be specific to the module (e.g., Finance, Logistics).
2
Locate the configuration settings for the preprocessor that is encountering the error. This could involve checking tables like `T7791` (for workflow settings) or module-specific configuration tables.
3
Verify that the preprocessor is correctly linked to the document type or business process it's intended for. Ensure there are no conflicting configurations.
4
Check for any custom rules, validation logic, or mapping settings within the preprocessor configuration. Incorrectly defined rules can lead to this error.
5
If custom code (e.g., ABAP user exits or BAdIs) is involved in the preprocessor logic, review the code for potential errors, incorrect data handling, or deviations from expected logic.
6
Make necessary adjustments to the preprocessor configuration. If custom code is the issue, work with a developer to debug and fix the code.
7
Save the changes and re-test the document processing.
3. Check for SAP Notes and Updates medium
Applies relevant SAP Notes or system updates that address known issues with document preprocessors.
1
Access the SAP Support Portal (launchpad.support.sap.com).
2
Search for SAP Notes related to error code 5536, 'ERR_TEXT_PREPROCESSOR_INVALID_INPUT_DOCUMENT', and the specific SAP S/4HANA module or business process involved.
3
Analyze the search results for relevant SAP Notes that describe the error and provide solutions, such as corrections to preprocessor logic or data handling.
4
If a relevant SAP Note is found, review its prerequisites and implementation instructions carefully.
5
Implement the SAP Note using the SAP Solution Manager or by manually applying the correction instructions in your SAP S/4HANA system. This typically involves importing transports.
6
After implementing the SAP Note, perform a thorough test of the document processing scenario.
7
Consider checking for recent SAP S/4HANA Support Packages or Feature Packages, as these often include fixes for known issues. Consult your SAP Basis team for upgrade or patch information.
