SAP S/4HANA Error 2825: SQLScript Signature Mismatch
Description
This error indicates that a SQLScript procedure, function, or view called by an SAP S/4HANA process has a definition (its signature, including parameters and return types) that does not match its corresponding entry in the HANA database catalog. This typically occurs when the object definition is updated but dependent calling objects or the catalog are not properly synchronized or activated.
Error Message
ERR_SQLSCRIPT_SIGNATURE_MISMATCH_WITH_CATALOG
Known Causes
3 known causesSQLScript Signature Modification
The parameters or return type of a SQLScript procedure or function were changed without properly activating or synchronizing all dependent objects.
Incomplete Object Deployment
SQLScript objects were transported or deployed to a new environment without all dependent objects, leading to a catalog mismatch.
Database Catalog Inconsistency
Rare instances where the HANA database catalog entries for SQLScript objects become corrupted or out of sync with the actual object definitions.
Solutions
3 solutions available1. Recompile the SQLScript Object easy
Recompiling the affected SQLScript object in the database often resolves signature mismatches.
1
Identify the specific SQLScript object (e.g., stored procedure, function, view) that is causing the error. This information is usually available in the application logs or the trace file associated with the error.
2
Connect to the SAP HANA database using a suitable client tool (e.g., SAP HANA Studio, Database Explorer in SAP Business Application Studio, or hdbsql).
3
Execute the `ALTER SYSTEM RECOMPILE` statement for the identified SQLScript object. Replace `<schema_name>` with the schema where the object resides and `<object_name>` with the name of the SQLScript object.
ALTER SYSTEM RECOMPILE '<schema_name>.<object_name>';4
Verify if the error is resolved by re-executing the operation that previously triggered the error.
2. Synchronize Development and Production Environments medium
Ensure that the SQLScript object deployed in the production environment matches the definition in the development or transport system.
1
Compare the definition of the SQLScript object in the target (production) system with its definition in the source (development or transport) system. This can be done by exporting the object definition from both systems and performing a diff.
2
If discrepancies are found, re-transport or re-deploy the correct version of the SQLScript object from the development/transport system to the production system. This typically involves using SAP transport management tools (e.g., STMS) or deployment tools specific to your development environment.
3
After deployment, recompile the object in the target system using the `ALTER SYSTEM RECOMPILE` command as described in the previous solution to ensure it's correctly registered.
ALTER SYSTEM RECOMPILE '<schema_name>.<object_name>';4
Test the functionality to confirm the error is resolved.
3. Update SAP HANA Database and Application Components advanced
Outdated database components or application versions can lead to signature mismatches.
1
Check for available SAP Notes and Support Packages for your SAP S/4HANA version and the underlying SAP HANA database. Pay close attention to notes related to SQLScript, database catalog, and specific application components that utilize the affected SQLScript object.
2
Plan and apply the relevant SAP Notes and Support Packages to both the SAP S/4HANA application layer and the SAP HANA database. This is a critical maintenance activity and should be performed during a scheduled downtime window.
3
After applying updates, restart the SAP HANA database and the S/4HANA application services.
4
Recompile all affected SQLScript objects or consider a full recompile of relevant schemas if the scope of the issue is broad. This ensures all objects are in sync with the updated database catalog.
ALTER SYSTEM RECOMPILE SCHEMA '<schema_name>';5
Thoroughly test all business processes that involve the SQLScript object and related functionalities.
