SAP S/4HANA Error 5158: Invalid Data Type Read
Description
Error 5158, ERR_TEXT_COMMON_INVALID_TYPE_DURING_READ, signifies that SAP S/4HANA attempted to read data from a stream but found an unexpected or incorrect data type. This often happens when integrating systems, processing external files, or during custom program execution where data formats do not match the expected specifications.
Error Message
ERR_TEXT_COMMON_INVALID_TYPE_DURING_READ
Known Causes
3 known causesData Type Mismatch in Integration
When integrating SAP S/4HANA with external systems, the data types sent by the external system do not match the expected types in S/4HANA.
Incorrect File Data Format
Attempting to import or process a file (e.g., CSV, XML) where the data within the file does not conform to the expected data type for specific fields.
Custom Code Data Handling Issue
Custom ABAP programs or extensions within S/4HANA are attempting to read data using an incorrect type specifier, leading to a mismatch during stream processing.
Solutions
3 solutions available1. Verify Data Type Mismatch in SAP Tables medium
Investigate and correct inconsistencies between ABAP data types and underlying database column types.
1
Identify the specific SAP table and field causing the error. This information is usually available in the application log or developer trace (dev_w*).
2
Access the SAP system's Data Dictionary (transaction SE11).
3
Enter the table name and display its structure.
4
Examine the data type and length of the field reported in the error. Compare this to the actual data type and length defined in the underlying database table. You can check the database definition using SQL commands if you have direct access.
SELECT column_name, data_type, data_length FROM ALL_TAB_COLUMNS WHERE table_name = 'YOUR_SAP_TABLE_NAME' AND column_name = 'YOUR_SAP_FIELD_NAME';5
If a mismatch is found, the most common cause is a direct database modification outside of SAP's controlled transport process. This is highly discouraged. Corrective actions depend on the situation:
6
For minor discrepancies (e.g., character set differences), it might be possible to adjust the database column definition if the data is compatible. **Caution: This requires deep understanding and should only be done with extreme care and thorough testing.** Consult SAP Notes for specific guidance on data type conversions.
ALTER TABLE YOUR_SAP_TABLE_NAME MODIFY (YOUR_SAP_FIELD_NAME VARCHAR2(50 CHAR)); -- Example for Oracle, adjust for your database7
If data corruption has occurred due to the mismatch, a data correction or re-import might be necessary. This typically involves SAP support or specialized data cleansing tools.
8
The ideal long-term solution is to revert any unauthorized direct database changes and ensure all schema modifications are performed through SAP's standard transport management system.
2. Review SAP Notes for Known Issues and Patches easy
Check for SAP Notes related to Error 5158 or data type issues in your S/4HANA version.
1
Log in to the SAP Support Portal (support.sap.com).
2
Navigate to the 'SAP Notes' section.
3
Search for 'Error 5158' or 'ERR_TEXT_COMMON_INVALID_TYPE_DURING_READ'. Also, search for terms like 'data type read error', 'invalid type', and your specific S/4HANA version (e.g., 'S/4HANA 2023 data type').
4
Carefully read the relevant SAP Notes. They may describe known bugs, provide workarounds, or offer correction instructions (e.g., applying a support package or implementing a specific correction instruction).
5
If a relevant SAP Note is found, follow its instructions precisely. This might involve applying a patch via transaction SNOTE or manually implementing correction instructions.
3. Analyze Application Logs and Developer Traces medium
Utilize system logs to pinpoint the exact context of the error.
1
Access the application log in the SAP system using transaction SLG1. Filter by the relevant object and subobject (often related to the application component experiencing the error).
2
Look for entries with the error message 'ERR_TEXT_COMMON_INVALID_TYPE_DURING_READ' and error code '5158'. The log entries should provide more context, including the program name, transaction code, and potentially the specific table and field involved.
3
If SLG1 doesn't provide enough detail, enable and analyze developer traces (dev_w* files) for the work process that encountered the error. These traces are located in the SAP instance's work directory on the application server.
4
Use the `grep` command (on Linux/Unix) or `Findstr` (on Windows) to search for the error code and message within the trace files.
grep '5158' dev_w*5
The trace files will often contain detailed information about the SQL statement being executed, the data being read, and the ABAP data structures involved, which can help in identifying the root cause of the type mismatch.
