SAP S/4HANA Error 1307: Invalid SQLScript Data Type
Description
This error indicates that an unsupported data type has been used within an SQLScript statement, function, or procedure in SAP S/4HANA, specifically when interacting with the underlying SAP HANA database. It commonly occurs during the development or execution of custom reports, extensions, or calculations involving direct SQLScript manipulation.
Error Message
ERR_SQLSCRIPT_UNSUPPORTED_DATATYPE
Known Causes
3 known causesIncorrect Data Type Usage
A data type used in SQLScript (e.g., in variable declarations, function parameters, or table definitions) is not recognized or supported by the SAP HANA database.
SAP HANA Version Incompatibility
The SQLScript code uses a data type that is either deprecated or not yet supported in the specific version of SAP HANA powering your S/4HANA system.
Custom Logic Error
Within a custom SQLScript procedure or function, an attempt is made to process or store data using an incompatible or non-existent data type.
Solutions
3 solutions available1. Adjust Data Type in SQLScript Procedure medium
Modify the data type of a parameter or variable within the SQLScript procedure to a supported type.
1
Identify the SQLScript procedure that is causing the error. This can often be found in the application logs or the error message itself.
2
Open the SQLScript procedure in the SAP HANA Studio or SAP Business Application Studio for editing.
3
Locate the parameter or variable declaration that uses an unsupported data type. Common culprits include complex user-defined types or specific HANA-specific types that might have changed or are not universally supported in S/4HANA SQLScript contexts.
Example of a problematic declaration:
DECLARE my_complex_var MY_UDT;
Example of a potentially problematic parameter:
PROCEDURE my_proc (IN input_param MY_SPECIAL_TYPE)4
Replace the unsupported data type with a standard SQL data type that is compatible with S/4HANA. For example, if you were using a complex UDT, you might need to break it down into its constituent standard types (e.g., VARCHAR, INTEGER, DECIMAL). If it's a specific HANA type, consult the S/4HANA SQLScript documentation for its supported equivalent.
Example of a corrected declaration:
DECLARE my_varchar_var VARCHAR(100);
Example of a corrected parameter:
PROCEDURE my_proc (IN input_param VARCHAR(255))5
Save and activate the modified SQLScript procedure.
6
Re-execute the operation that triggered the error to verify the fix.
2. Update Application Code Interfacing with SQLScript medium
Modify the calling application code to pass data using supported types when invoking the SQLScript procedure.
1
Determine which application component or service is calling the problematic SQLScript procedure.
2
Examine the code that prepares and passes parameters to the SQLScript procedure. This could be ABAP, Java, or another language used in your S/4HANA landscape.
Example ABAP snippet (conceptual):
DATA: lv_complex_data TYPE MY_UDT.
CALL METHOD cl_sql_statement=>execute_procedure(
EXPORTING...
IMPORTING...
TABLES...
USING my_proc(
input_param = lv_complex_data
)
).3
If the application is passing a variable of an unsupported data type, refactor the application code to convert or represent that data using standard SQL data types before passing it to the procedure. This might involve manual data manipulation or using appropriate conversion functions provided by the application language.
Example ABAP snippet (conceptual correction):
DATA: lv_varchar_data TYPE VARCHAR(100).
" Logic to populate lv_varchar_data from the original complex data.
CALL METHOD cl_sql_statement=>execute_procedure(
EXPORTING...
IMPORTING...
TABLES...
USING my_proc(
input_param = lv_varchar_data
)
).4
Deploy the updated application code.
5
Test the application functionality to ensure the error is resolved.
3. Consult S/4HANA and HANA Database Documentation easy
Review official SAP documentation for supported data types in SQLScript for your specific S/4HANA version.
1
Identify the exact version of your SAP S/4HANA system and the underlying SAP HANA database version.
2
Access the SAP Help Portal (help.sap.com) and navigate to the documentation for your specific S/4HANA version.
3
Search for documentation related to 'SQLScript', 'Data Types', or 'Programming Guide' for SAP HANA.
4
Carefully review the list of supported data types for SQLScript procedures and functions. Pay attention to any version-specific notes or deprecated types.
5
If you discover that a data type used in your SQLScript or application is indeed unsupported, use the documentation to identify the correct, supported alternative.
6
Apply the necessary changes to your SQLScript procedures or application code based on the documented supported types.
