SAP S/4HANA Error 603: Invalid LOB Parameter
Description
Error 603 (ERR_API_INV_LOB) indicates that an API call within SAP S/4HANA received an invalid Large Object (LOB) parameter. This typically occurs when data sent to an API does not conform to the expected type, format, or size for LOB fields, preventing the API from processing the request correctly.
Error Message
ERR_API_INV_LOB
Known Causes
4 known causesLOB Data Type Mismatch
The Large Object data provided in the API request does not match the expected data type defined for that parameter by the SAP S/4HANA API.
Incorrect LOB Data Format
The LOB data, while potentially of the correct type, is malformed or does not adhere to the specific format or schema required by the API.
LOB Data Size Exceeded
The size of the Large Object data sent in the API call surpasses the maximum limit allowed for that particular parameter by the SAP S/4HANA system.
Misconfigured API Parameter
The LOB data is being passed to an incorrect API parameter, or the parameter mapping in the integration setup is erroneous.
Solutions
3 solutions available1. Validate and Correct LOB Data Types in Application Code medium
Ensures that Large Object (LOB) data types are correctly handled and declared within the SAP S/4HANA application layer.
1
Identify the specific ABAP program or function module that is triggering the ERR_API_INV_LOB error. This often involves analyzing the ST22 dumps or SM21 logs.
2
Examine the data declarations for any parameters that handle LOB data (e.g., `STRING`, `XSTRING`, `SOLIX`, `SOLIX_TAB`). Ensure they are declared with appropriate types and lengths for the data being processed.
ABAP Example (Illustrative - actual code will vary):
DATA lv_clob_data TYPE string.
DATA lv_blob_data TYPE xstring.3
If the error occurs during data insertion or update, verify that the LOB data being passed to the database is not exceeding any defined maximum limits for the database column or the application's internal representation.
4
Review any custom code that interacts with LOB fields. Incorrect handling of pointer types, length indicators, or data conversion issues can lead to this error.
5
Re-activate the relevant ABAP objects after making corrections. Test the functionality thoroughly to confirm the error is resolved.
2. Check Database Table and Column Definitions for LOBs medium
Verifies that the underlying SAP S/4HANA database table and column definitions for LOBs are consistent and correctly configured.
1
Use the ABAP Dictionary (transaction SE11) to inspect the table structure containing the LOB data. Identify the specific table and the LOB column(s).
2
Examine the data type of the LOB column. For example, it might be `CLOB` (Character Large Object) or `BLOB` (Binary Large Object). Ensure this aligns with the application's expectations.
3
If the table was modified outside of standard SAP processes (e.g., direct SQL modifications), ensure that the LOB column's properties (like max size, if applicable) are set correctly. This is less common in S/4HANA but possible in rare scenarios.
4
If you suspect a corruption or inconsistency, consider using database-specific tools to check the integrity of the LOB data within the table. For HANA, this might involve specific `REPAIR` or `CHECK` commands if available and applicable to LOBs, or consulting SAP Notes for specific procedures.
3. Investigate SAP Notes and OSS Messages Related to LOB Handling easy
Leverages SAP's knowledge base to identify known issues and solutions for ERR_API_INV_LOB.
1
Go to SAP Support Portal (support.sap.com) and search for SAP Notes using keywords like 'ERR_API_INV_LOB', '603', 'invalid LOB parameter', and relevant SAP S/4HANA versions or transaction codes.
2
Analyze the search results for notes that describe similar error scenarios or address specific bugs in LOB handling for your SAP S/4HANA release.
3
If a relevant SAP Note is found, carefully follow the instructions provided. This might involve applying a support package, a specific correction (SAP Note implementation), or a configuration change.
4
If no direct SAP Note is found, consider raising an incident with SAP Support. Provide detailed information about the error, including the exact error message, transaction code, user, and any relevant ST22 dumps.
