SAP S/4HANA Error 1336: SQLScript Runtime Exception
Description
Error 1336 indicates an unexpected internal exception occurred during the execution of an SAP HANA SQLScript runtime procedure within SAP S/4HANA. This typically points to a deeper issue within the SQLScript logic or the underlying database environment, preventing the successful completion of a process.
Error Message
ERR_SQLSCRIPT_RUNTIME_UNEXPECTED_EXCEPTION
Known Causes
4 known causesFlawed Custom SQLScript Logic
A bug or logical error in custom-developed SQLScript procedures can lead to unexpected runtime failures when executed within SAP S/4HANA processes.
Insufficient System Resources
Lack of available memory, CPU, or temporary disk space on the SAP HANA database server can cause a SQLScript procedure to terminate unexpectedly.
Invalid Input Data
The SQLScript procedure might encounter data that violates its assumptions or constraints, leading to an unexpected exception during processing.
Underlying Database Issue
Rarely, an internal issue or bug within the SAP HANA database engine itself can manifest as an unexpected SQLScript runtime exception.
Solutions
4 solutions available1. Analyze SQLScript Trace and Logs medium
Investigate detailed execution information to pinpoint the root cause of the runtime exception.
1
Identify the specific SQLScript procedure or function that is failing. This can often be found in the application logs or by correlating with the error timestamp.
2
Access the SQLScript trace for the failing operation. In SAP HANA, you can use the SQLScript tracing tools available through SAP HANA Studio or the SAP HANA Cockpit. Enable tracing for the specific user or session experiencing the error.
Example of enabling tracing in HANA Studio (GUI-based, no direct SQL snippet for this initial setup):
1. Open SAP HANA Studio.
2. Connect to your SAP HANA system.
3. Navigate to 'Administration' perspective.
4. Select your system and go to 'Performance' -> 'SQL Trace'.
5. Click 'New Trace' and configure the parameters to capture the relevant execution.3
Analyze the generated trace file. Look for the exact SQL statement or code block that triggered the exception. The trace will often provide more granular error messages or context than the initial 1336 error.
4
Examine relevant SAP system logs (e.g., ST22 for ABAP dumps if the SQLScript is called from ABAP) and SAP HANA trace files (e.g., indexserver traces) for additional clues. Correlate timestamps to identify related events.
2. Validate Data Types and Input Parameters easy
Ensure that the data types of input parameters and internal variables match expectations to prevent runtime mismatches.
1
Review the definition of the failing SQLScript procedure or function. Pay close attention to the data types of all input parameters and any internal variables used.
2
Compare the data types of the values being passed into the SQLScript from the calling application (e.g., SAP S/4HANA ABAP layer, another SQLScript, or an external system) with the expected data types in the SQLScript definition.
3
If a mismatch is found, adjust the data type conversions in either the calling application or within the SQLScript itself. Explicit type casting can often resolve these issues.
Example of explicit type casting within SQLScript:
-- Assuming 'input_param' is expected to be an integer, but might be passed as a string
DECLARE my_integer_var INTEGER;
my_integer_var = CAST(input_param AS INTEGER);
-- Or if a numerical calculation expects a decimal, but receives an integer:
DECLARE result DECIMAL(10,2);
result = CAST(some_integer_value AS DECIMAL(10,2)) * 0.5;4
Test the SQLScript with various valid and potentially problematic input values to ensure robustness.
3. Check for Database Object Dependencies and Permissions medium
Verify that all referenced database objects exist and that the user executing the SQLScript has the necessary privileges.
1
Identify all database objects (tables, views, other procedures, functions) that are accessed by the failing SQLScript. This information is usually available in the SQLScript code itself.
2
Verify the existence of these dependent objects in the SAP HANA database. Use SQL queries to check if they are present and accessible.
SELECT * FROM SYS.OBJECTS WHERE OBJECT_NAME = 'YOUR_TABLE_NAME' AND SCHEMA_NAME = 'YOUR_SCHEMA_NAME';3
Confirm that the user or role executing the SQLScript has been granted the necessary privileges (e.g., SELECT, INSERT, UPDATE, DELETE, EXECUTE) on these dependent objects. This is crucial if the SQLScript is executed by an application user or a specific role.
SELECT * FROM SYS.GRANTED_PRIVILEGES WHERE GRANTEE = 'YOUR_USER_OR_ROLE_NAME' AND OBJECT_NAME = 'YOUR_TABLE_NAME';4
If the SQLScript calls another stored procedure or function, ensure that it has EXECUTE permission on that object.
SELECT * FROM SYS.GRANTED_PRIVILEGES WHERE GRANTEE = 'YOUR_USER_OR_ROLE_NAME' AND OBJECT_NAME = 'YOUR_PROCEDURE_NAME' AND PRIVILEGE = 'EXECUTE';5
If any objects are missing or privileges are insufficient, work with your SAP HANA administrator to create the objects or grant the necessary permissions.
4. Review and Optimize Complex SQLScript Logic advanced
Simplify or optimize intricate SQLScript code that might be causing unforeseen runtime issues.
1
Analyze the SQLScript code for any complex JOIN operations, subqueries, cursors, or recursive logic that could be prone to errors or performance bottlenecks.
2
Use the SAP HANA Explain Plan for the failing SQLScript to understand its execution path and identify potential performance issues or problematic query segments.
EXPLAIN PLAN FOR <your_failing_sqlscript_call>;3
Consider breaking down very large or complex SQLScript procedures into smaller, more manageable units. This can improve readability and isolate potential errors.
4
If cursors are used, evaluate if they can be replaced with set-based operations, which are generally more efficient in SQL.
5
Ensure that any temporary tables or table variables used within the SQLScript are properly declared, populated, and dropped when no longer needed to avoid resource exhaustion or unexpected behavior.
6
If the SQLScript is part of a custom development, consult with the development team to review the logic and ensure it adheres to best practices for SAP HANA development.
