SAP S/4HANA Error 1357: Handle CE Function Type Mismatch
Description
This error indicates an incompatibility between the data types of columns or expressions used within a Calculation Engine (CE) function in an SAP HANA SQLScript. It typically occurs when an operation expects a specific data type (e.g., numeric) but receives another (e.g., string), preventing the function from executing correctly.
Error Message
ERR_SQLSCRIPT_CE_TYPE_MISMATCH
Known Causes
3 known causesIncorrect Column Data Type
A table column referenced within the CE function has a data type that does not match the expected type for the operation.
Mismatched Expression Arguments
Data types of expressions or variables passed as arguments to the CE function do not align with the function's parameter expectations.
Implicit Conversion Failure
The SAP HANA database was unable to perform an automatic (implicit) data type conversion between elements used in the CE function.
Solutions
3 solutions available1. Reactivate HANA Calculation View easy
Reactivating a HANA Calculation View often resolves type mismatches by forcing a revalidation of its structure and dependencies.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to the transaction code for HANA development tools. This is typically `SE80` and then selecting 'Development Information' -> 'HANA Development' -> 'HANA Development Tools'. Alternatively, you can use the web-based tools like SAP Business Application Studio (BAS) or SAP HANA Studio.
3
Locate the specific Calculation View that is causing the error. You can search for it by its name or package.
4
Right-click on the Calculation View and select 'Activate' or a similar option. If using BAS, open the view and click the 'Activate' button.
5
Monitor the activation process for any errors. If the activation is successful, the type mismatch error should be resolved. If activation fails, note down any new error messages for further investigation.
2. Verify Data Types in Source Objects medium
This solution involves checking the data types of columns in the underlying tables or other views that feed into the problematic Calculation View.
1
Identify the Calculation View that is throwing the error `ERR_SQLSCRIPT_CE_TYPE_MISMATCH`.
2
Examine the graphical or script editor of this Calculation View to understand its data sources (tables, other views).
3
For each data source, access its definition. In SAP HANA Studio or BAS, you can right-click the source object and select 'Open Definition' or similar.
4
Compare the data types of the columns being used in the Calculation View's projection or join conditions with the actual data types defined in the source objects. Pay close attention to numeric types (e.g., DECIMAL, INTEGER), string types (e.g., VARCHAR, NVARCHAR), and date/time types.
5
If a type mismatch is found (e.g., a VARCHAR is expected but a DECIMAL is provided, or vice-versa), you will need to correct it. This might involve:
a) Modifying the Calculation View to cast or convert the data type using HANA SQL functions (e.g., `CAST()`, `TO_DECIMAL()`, `TO_VARCHAR()`).
b) If the mismatch is due to incorrect data in the source table, you might need to clean the source data or, if feasible, alter the source table's column data type (this is a more significant change and requires careful consideration).

After making any necessary corrections, reactivate the Calculation View (refer to Solution 1).
3. Update HANA Database and S/4HANA Components advanced
Ensuring your SAP HANA database and SAP S/4HANA components are on compatible and up-to-date versions can resolve underlying bugs that cause type mismatches.
1
Consult SAP Notes and the SAP Product Availability Matrix (PAM) to determine the recommended SAP HANA database version for your specific SAP S/4HANA version and support package.
2
Plan and schedule a maintenance window for the database upgrade. This is a critical operation and requires thorough testing.
3
Perform the SAP HANA database upgrade following SAP's official upgrade guides. This typically involves using the HANA Lifecycle Manager (HLM) or command-line tools.
4
After the HANA database upgrade, check for any required SAP S/4HANA Support Package Stack (SPS) upgrades or specific SAP Notes that need to be implemented to ensure compatibility.
5
Apply any necessary S/4HANA component updates or implement relevant SAP Notes. This might involve running transaction `SPAM` or `SAINT` for ABAP Support Packages and Notes.
6
After all updates are applied, reactivate all affected Calculation Views and other HANA objects. Test the functionality thoroughly to confirm the error is resolved.
