SAP S/4HANA Error 5175: Invalid XML Buffer Length
Description
Error 5175, ERR_TEXT_COMMON_INVALID_INPUT_BUFFER_LENGTH, indicates that the length of an XML input stream being processed by SAP S/4HANA is invalid. This typically occurs when the system receives XML data that does not match the expected buffer size, preventing successful parsing or processing.
Error Message
ERR_TEXT_COMMON_INVALID_INPUT_BUFFER_LENGTH
Known Causes
3 known causesIncorrect XML Payload Size
The size of the XML data being processed does not match the expected buffer length configured for the input stream within SAP S/4HANA.
Data Truncation or Corruption
The XML input stream was partially received or corrupted during transmission, leading to an unexpected and invalid buffer length.
Misconfigured System Parameters
System or interface settings within SAP S/4HANA or connected applications specify an incorrect buffer size limit for XML processing.
Solutions
3 solutions available1. Increase XML Buffer Size in SAP Instance Profile easy
Adjust the instance profile parameter to allow for larger XML data.
1
Log in to your SAP S/4HANA system with an administrator user.
2
Access transaction `RZ10` (Parameter Maintenance).
3
Select the relevant instance profile (e.g., `DEFAULT.PFL` or the specific instance profile).
4
Click 'Change' to edit the profile.
5
Navigate to 'Extended maintenance' and then 'Single parameter'.
6
Search for the parameter `icm/HTTP/max_request_size_KB`. If it doesn't exist, create it.
7
Increase the value of `icm/HTTP/max_request_size_KB` to accommodate larger XML payloads. A common starting point is to double or triple the current value, or set it to a sufficiently large number (e.g., 50000 KB or higher, depending on your needs).
icm/HTTP/max_request_size_KB = 500008
Save the changes to the profile.
9
Activate and generate the profile. You will be prompted to restart the ICM (Internet Communication Manager) or the entire application server instance for the changes to take effect.
10
Restart the ICM (transaction `SMICM` -> Administration -> ICM -> Exit Soft) or the application server instance. Confirm the restart when prompted.
2. Optimize XML Data Size at Source medium
Reduce the size of the XML data being sent to SAP S/4HANA.
1
Identify the specific interface or transaction that is generating the large XML payload. This might involve analyzing SAP application logs (e.g., `SM21`), trace files, or debugging the relevant ABAP code.
2
Examine the structure and content of the XML. Look for redundant data, unnecessary fields, or large repetitive elements.
3
If possible, modify the sending application or the data generation process to send only essential data. This could involve:
- Removing optional fields that are not required by the SAP S/4HANA interface.
- Compressing repetitive data structures if the receiving interface supports it.
- Filtering data at the source to include only relevant records.
- Removing optional fields that are not required by the SAP S/4HANA interface.
- Compressing repetitive data structures if the receiving interface supports it.
- Filtering data at the source to include only relevant records.
4
If the XML is generated by an external system, work with the external system's developers to implement these optimizations.
5
If the XML is generated by an SAP ABAP program, review and modify the ABAP code to generate a more concise XML output.
Example ABAP snippet (conceptual):
DATA: lv_xml_string TYPE string.
' '" Build XML structure here, ensuring to only include necessary data.
' '" For example, avoid exporting internal tables with millions of rows if only a summary is needed.
CALL TRANSFORMATION id FROM lv_xml_structure INTO lv_xml_string.
' '" Then use lv_xml_string in your interface call.6
Test the optimized XML generation and the interface call to ensure the error is resolved.
3. Review and Adjust XML Transformation Settings medium
Fine-tune parameters related to XML parsing and processing within SAP.
1
Identify the specific SAP component or module that is processing the XML. This could be an ABAP program, an SAP PI/PO interface, or an OData service.
2
For ABAP-based XML processing, check the parameters used in `CALL TRANSFORMATION` or other XML parsing functions. Some transformations might have options to control buffer sizes or parsing strategies.
3
If using SAP Process Integration/Process Orchestration (PI/PO), examine the relevant message mappings and adapters. Some adapters might have configuration settings related to buffer sizes or chunking of large messages.
4
For OData services, investigate the service implementation. The underlying ABAP code might be generating or processing the XML. Check for any explicit buffer size limitations within the service implementation.
5
Consult SAP Notes related to XML processing and buffer limits for the specific SAP S/4HANA version and components involved. SAP often provides specific recommendations or corrections for such issues.
6
If a specific parameter is identified (e.g., within an adapter configuration or a custom ABAP program), adjust it to allow for larger XML data. This might involve increasing a buffer size or changing a processing mode.
7
Thoroughly test the interface after making any adjustments to transformation or processing settings.
