SAP S/4HANA Error 458: Unsupported SQL Function Call
Description
Error 458, ERR_SQL_UNSUPPORTED_FUNCTION, indicates that an SQL query or statement executed within SAP S/4HANA contains a function that is not recognized or supported by the underlying SAP HANA database. This typically occurs when custom code, reports, or third-party integrations attempt to use database functions outside of the standard supported set for the current SAP HANA version.
Error Message
ERR_SQL_UNSUPPORTED_FUNCTION
Known Causes
3 known causesCustom SQL Function Usage
A custom report, application, or integration attempts to execute an SQL statement containing a function not supported by the SAP HANA database.
Database Version Incompatibility
The SQL function might be valid in a different database version or dialect but is not available in the specific SAP HANA version used by S/4HANA.
Incorrect SQL Dialect
The SQL statement uses syntax or functions specific to a different database system (e.g., Oracle, SQL Server) that are not compatible with SAP HANA SQL.
Solutions
3 solutions available1. Replace Unsupported SQL Function with S/4HANA Compatible Alternative medium
Identify and replace the problematic SQL function with an equivalent or supported function within the SAP S/4HANA environment.
1
Identify the exact SQL function causing the error. This usually involves checking the application logs (SM21, ST22) or the trace files of the application component that triggered the error. Look for the specific function name mentioned in the error message or surrounding SQL statements.
2
Consult SAP Notes and S/4HANA documentation to determine if the function is indeed unsupported or has been deprecated. Search for the function name along with terms like 'unsupported', 'deprecated', 'S/4HANA SQL', or 'HANA SQL'. SAP Notes often provide alternative functions or workarounds.
3
If a direct alternative is not immediately obvious, analyze the intended functionality of the unsupported function. Explore standard S/4HANA SQL functions or even ABAP constructs that can achieve the same result. For instance, a complex string manipulation function might be replaceable by a combination of simpler string functions or an ABAP routine.
4
Modify the SQL query or ABAP code to use the identified compatible alternative. This might involve changing the function name, adjusting parameters, or restructuring the query logic. For example, if a deprecated Oracle function was used, you might need to replace it with a native SAP HANA SQL function.
-- Example: Replacing a hypothetical unsupported function 'OLD_FUNCTION' with a HANA equivalent 'NEW_FUNCTION'
SELECT NEW_FUNCTION(column_name) FROM table_name WHERE condition;5
Test the modified query or application thoroughly in a development or quality assurance environment to ensure it functions correctly and resolves the error without introducing new issues.
2. Review and Update Custom SQL or CDS Views for S/4HANA Compatibility advanced
Adapt custom SQL statements and Core Data Services (CDS) views to adhere to S/4HANA's SQL dialect and best practices.
1
Identify all custom SQL statements or CDS views that are being used by the S/4HANA system. This can be done by reviewing custom code, checking for SQL traces, or using tools like the SAP HANA SQL Analyzer.
2
For custom SQL statements, carefully examine each one for the use of functions that are not part of the SAP HANA SQL standard or are specifically disallowed in S/4HANA. Pay attention to functions that might have been supported in older SAP databases (e.g., Oracle, SQL Server) but are not in HANA.
3
For CDS views, use the ABAP Development Tools (ADT) in Eclipse to analyze their syntax and annotations. ADT provides features to check for compatibility issues and highlight unsupported elements. Ensure you are using the latest CDS annotations and syntax that are compatible with your S/4HANA version.
4
Rewrite or refactor the problematic SQL statements or CDS views. Leverage SAP HANA's native SQL capabilities and CDS features. For instance, instead of relying on procedural SQL extensions, consider using analytical functions or structured SQL expressions. For CDS, explore annotations like @ObjectModel.is.active and @Analytics.dataCategory for better performance and compatibility.
-- Example of a potential CDS view improvement for compatibility:
@AbapCatalog.sqlViewName: 'MYVIEW'
@AbapCatalog.compiler.hint: 'X'
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'My S/4HANA Compatible View'
define view Z_MY_COMPATIBLE_VIEW as select from some_table {
key field1,
field2
-- Use HANA-native functions or constructs here
};5
Thoroughly test the modified custom SQL and CDS views in a non-production environment. Run relevant business processes that utilize these objects to confirm they are working as expected and that the 'Unsupported SQL Function Call' error is resolved.
3. Investigate and Update SAP Standard Objects with SAP Support advanced
If the error originates from SAP standard objects, engage SAP support for guidance and potential patches.
1
Reproduce the error in a controlled environment and gather detailed information, including the transaction code, the exact error message, and any relevant application logs (SM21, ST22) or trace files (ST05).
2
Search SAP Notes for the specific error code (458) and message. It's possible that SAP has already identified this issue in a standard object and provided a solution via a support package or a note.
3
If no relevant SAP Note is found, create a support ticket with SAP. Provide all the collected information, including the steps to reproduce the error, relevant logs, and the exact SQL function that is causing the problem. Clearly state that you are encountering an 'Unsupported SQL Function Call' in S/4HANA.
4
Follow the guidance provided by SAP support. This may involve applying a specific SAP Note, implementing a correction program, or waiting for a future support package that addresses the issue.
5
After applying any recommended changes from SAP support, thoroughly test the affected functionality to confirm that the error is resolved and no regressions have been introduced.
