SAP S/4HANA Error 1330: Syntax in Calculated Attributes
Description
Error 1330, ERR_SQLSCRIPT_BUILTIN_CALCATTR_EXPRESSION_SYNTAX, indicates a syntax error within a calculated attribute's expression in SAP S/4HANA. This typically occurs when defining or activating views, queries, or other data models that utilize SQLScript for deriving new attributes.
Error Message
ERR_SQLSCRIPT_BUILTIN_CALCATTR_EXPRESSION_SYNTAX
Known Causes
4 known causesIncorrect SQLScript Syntax
The expression defined for the calculated attribute contains fundamental errors in SQLScript syntax, preventing proper parsing and execution.
Invalid Function Usage
An SQLScript function is used incorrectly, with wrong parameters, data types, or in an inappropriate context within the expression.
Missing or Mismatched Operators
The expression is missing required operators, contains mismatched parentheses, or has incorrect operator precedence, leading to a parsing failure.
Referencing Non-existent Column
The calculated attribute expression attempts to reference a column or field that does not exist in the underlying data source or view.
Solutions
3 solutions available1. Review and Correct Calculated Attribute Syntax easy
This solution focuses on directly identifying and fixing syntax errors within the calculated attribute's expression.
1
Identify the specific calculated attribute causing the error. This might be indicated in more detailed logs or by tracing the execution flow leading to error 1330.
2
Access the definition of the calculated attribute within your SAP S/4HANA system. This is typically done through tools like SAP HANA Studio, SAP Business Application Studio, or by querying the system catalog views.
SELECT * FROM _SYS_REPO.OBJECT_SOURCES WHERE OBJECT_ID = '<your_object_id>' AND SOURCE_TYPE = 'SQLSCRIPT';3
Carefully examine the expression used for the calculated attribute. Look for common syntax errors such as:
- Missing or misplaced parentheses.
- Incorrect use of operators (e.g., arithmetic, logical).
- Typos in function names or keywords.
- Incorrect data type conversions.
- Missing or incorrect delimiters for strings.4
Consult the SAP HANA SQL Reference documentation for the correct syntax of functions, operators, and data type casting relevant to your expression.
5
Correct the identified syntax errors in the calculated attribute's expression.
6
Deploy the corrected object back to your SAP S/4HANA system and re-test the functionality that triggered the error.
2. Validate Data Types and Implicit Conversions medium
This solution addresses potential issues arising from incompatible data types within the calculated attribute's expression.
1
Pinpoint the calculated attribute and the specific expression involved in error 1330.
2
Identify the data types of the columns or values used in the calculated attribute's expression. This can be done by querying the data dictionary or through your development environment.
SELECT COLUMN_NAME, DATA_TYPE FROM "_SYS_BIC"."<your_package_name>/<your_cds_view_name>" LIMIT 1;3
Analyze the expression for any operations that might require implicit data type conversions. SAP HANA has rules for implicit conversions, but they can sometimes lead to unexpected results or syntax errors if not handled correctly.
4
Explicitly cast data types where necessary to ensure compatibility. For example, if you are performing arithmetic operations on a string column, cast it to a numeric type.
CAST(<column_name> AS DECIMAL(10,2))5
Rewrite the calculated attribute's expression to use explicit type conversions for all potentially problematic operations.
6
Deploy the updated object and verify that the error is resolved.
3. Simplify Complex Expressions and Test Sub-expressions medium
This proactive approach helps to isolate the source of syntax errors in complex calculated attributes.
1
If the calculated attribute's expression is very complex, break it down into smaller, more manageable sub-expressions.
2
Test each sub-expression individually to verify its syntax and expected output. You can do this by creating temporary views or by executing the sub-expressions directly in a SQL console.
SELECT <sub_expression> FROM <your_table> LIMIT 10;3
As you test each sub-expression, look for syntax errors that might have been masked by the overall complexity of the original expression.
4
Once the problematic sub-expression is identified, focus on correcting its syntax as described in Solution 1.
5
Gradually re-integrate the corrected sub-expressions into the main calculated attribute expression, testing at each stage.
6
Deploy the fully corrected calculated attribute and confirm the error is gone.
