SAP S/4HANA Error 1298: Unhandled SQLScript Exception
Description
This error indicates that an exception raised within an SAP HANA SQLScript procedure or function was not caught by a `CATCH` block. It typically points to a defect in custom code where a specific error condition was not anticipated or handled gracefully, leading to an abrupt termination of the process.
Error Message
ERR_SQLSCRIPT_UNHANDLED_EXCEPTION
Known Causes
3 known causesUncaught Custom Exception
A user-defined exception was explicitly raised within an SAP HANA SQLScript procedure or function, but no `CATCH` block was present to handle it.
Missing Exception Handling
The SQLScript procedure or function lacks comprehensive `TRY...CATCH` blocks to manage potential errors during its execution.
Data Validation Failure
Invalid or unexpected input data led to an internal SQLScript error that was not properly caught and managed by the existing code.
Solutions
4 solutions available1. Analyze SQLScript Trace for Root Cause medium
Investigate the detailed SQLScript execution trace to pinpoint the exact statement causing the unhandled exception.
1
Identify the specific transaction or process that triggers error 1298. This is crucial for narrowing down the scope of the trace.
2
Activate SQLScript tracing for the relevant user or session. This can be done using transaction ST05 (Performance Analysis) or the SQL trace tools within SAP HANA Studio/Cockpit.
Activate trace for user <username> or session <session_id>.
3
Re-execute the transaction or process that caused the error while tracing is active.
4
Analyze the generated trace file (e.g., in ST05 or HANA Studio). Look for the SQLScript statement that immediately precedes the 'ERR_SQLSCRIPT_UNHANDLED_EXCEPTION'. Pay close attention to error messages within the trace related to that specific SQLScript.
5
Based on the trace analysis, identify the problematic SQLScript (e.g., a stored procedure, function, or script). You might see syntax errors, runtime errors (like division by zero, invalid data types), or logical errors within the script.
2. Review and Correct Faulty SQLScript Logic advanced
Examine the SQLScript identified in the trace and rectify any logical flaws, syntax errors, or data handling issues.
1
Locate the problematic SQLScript object in your SAP S/4HANA system. This could be a stored procedure, function, or a table function. You can use transaction SE80 (Object Navigator) or HANA Studio/Cockpit to find these objects.
2
Carefully review the SQLScript code for common errors such as:
- Division by zero (e.g., `10 / 0`)
- Type mismatches (e.g., assigning a string to a numeric variable)
- Null pointer exceptions (dereferencing a null value)
- Incorrect loop conditions
- Out-of-bounds array access
- Missing error handling for exceptions within the script itself (e.g., using `TRY...CATCH` blocks if supported and appropriate).
3
If the error is due to an unexpected input value, consider adding validation checks at the beginning of the SQLScript. For example, check if a divisor is zero before performing division.
IF :divisor = 0 THEN
-- Handle error or return a default value
RETURN 0;
END IF;
result = :numerator / :divisor;
4
If the error stems from a specific data scenario, try to replicate that scenario in a test environment and debug the SQLScript step-by-step. Use `SELECT` statements within the script to inspect intermediate values.
SELECT 'Intermediate value:', intermediate_variable FROM dummy;
5
Modify the SQLScript to correct the identified errors. Ensure the logic correctly handles all expected and unexpected data conditions.
6
Reactivate or recompile the corrected SQLScript object.
7
Test the transaction or process again to confirm the error is resolved.
3. Check for SAP Notes and Known Issues easy
Verify if the error is a known bug addressed by SAP Notes or patches.
1
Access the SAP Support Portal (SAP ONE Support Launchpad).
2
Search for SAP Notes using keywords like 'SAP S/4HANA', 'SQLScript Exception', 'Error 1298', and any specific function modules or transaction codes involved in the error.
3
Review the search results for relevant SAP Notes that describe the error 1298 or similar unhandled SQLScript exceptions. Pay attention to the 'Symptom' and 'Reason and Prerequisites' sections.
4
If a relevant SAP Note is found, check if it is already implemented in your system. If not, follow the instructions in the note to implement the necessary corrections or patches.
5
After implementing any recommended SAP Notes, test the affected functionality to ensure the error is resolved.
4. Verify Data Integrity and Consistency medium
Ensure that the data being processed by the SQLScript is valid and consistent, as data corruption can lead to unexpected script failures.
1
Identify the tables or data sources that the problematic SQLScript accesses. This information can often be found by analyzing the SQLScript code itself or by using the trace from Solution 1.
2
Perform data integrity checks on these tables. This might involve checking for duplicate entries, invalid foreign key relationships, or incorrect data types in specific columns.
SELECT COUNT(*) FROM <table_name> WHERE <column_name> IS NULL;
3
Use SAP S/4HANA or SAP HANA tools to validate data consistency. For example, check if referential integrity constraints are being violated.
4
If inconsistencies are found, use appropriate data correction tools or manual processes to fix the data. Be cautious and always back up data before making any modifications.
5
After correcting any data issues, re-run the transaction or process that was causing error 1298 to see if the problem is resolved.
