SAP S/4HANA Error 418: Invalid View Query Creation
Description
Error 418, 'ERR_SQL_INV_VIEW_QUERY', indicates that an attempt to create a database view in SAP S/4HANA failed due to an invalid SQL query. This typically occurs during development, configuration, or customization when defining new analytical or database views, preventing the system from processing the view definition.
Error Message
ERR_SQL_INV_VIEW_QUERY
Known Causes
4 known causesSQL Syntax Errors
The SQL statement defining the view contains incorrect keywords, missing punctuation, or malformed clauses that violate database syntax rules. 💻
Non-existent Objects
The view query references tables, columns, or other database objects that do not exist or are misspelled in the current database schema. 💻
Insufficient Authorization
The user attempting to create the view lacks the necessary database privileges to access the underlying tables or to create views in the specified schema. 🔒
Logical Query Inconsistency
While syntactically correct, the view query contains logical flaws, such as incompatible data types in joins or ambiguous column references, preventing successful view creation. ⚠
Solutions
3 solutions available1. Validate SQL Syntax for View Definition medium
Ensure the SQL statement used to define or query the view adheres to SAP HANA's SQL dialect and syntax rules.
1
Identify the specific view that is causing the error. This might be indicated in the application logs or the error message itself.
2
Access the view definition using SAP HANA Studio or SAP HANA Cockpit. Navigate to the relevant schema and find the view object.
3
Carefully review the SQL statement used for the view's SELECT clause. Pay close attention to:
4
1. **Keywords:** Ensure all keywords are spelled correctly and used appropriately (e.g., SELECT, FROM, WHERE, JOIN, GROUP BY, HAVING, ORDER BY).
5
2. **Identifiers:** Verify that table and column names are correctly quoted (if necessary) and that they exist in the schema. Case sensitivity might be a factor depending on HANA configuration.
6
3. **Functions:** Check for correct function names and argument types. SAP HANA has its own set of built-in functions.
7
4. **Operators:** Ensure that operators (e.g., =, <, >, AND, OR, IN, BETWEEN) are used with compatible data types.
8
5. **Subqueries and Joins:** Validate the syntax of any subqueries or join conditions. Ensure correct join types (INNER, LEFT, RIGHT, FULL) and ON clauses.
9
6. **Data Type Compatibility:** Confirm that expressions and comparisons involve compatible data types. Implicit type conversions might not always be supported or desired.
10
Execute the SQL query directly in SAP HANA Studio or through a SQL client to pinpoint the exact syntax error.
SELECT * FROM YOUR_VIEW_NAME;11
Correct any identified syntax errors in the view definition or in the query that is attempting to use the view.
2. Check for Invalid Object References in View medium
Ensure that the view definition references valid and accessible database objects (tables, other views, functions).
1
Locate the view definition in SAP HANA Studio or SAP HANA Cockpit.
2
Examine the `FROM` and `JOIN` clauses of the view's SQL query.
3
Verify that all referenced tables, views, and functions actually exist within the schema where the view is defined or are accessible via synonyms/permissions.
4
If a referenced object has been dropped, renamed, or its schema changed, the view definition will become invalid.
5
Use the following SQL query to check the dependencies of the view. Replace `YOUR_SCHEMA_NAME` and `YOUR_VIEW_NAME`.
SELECT * FROM SYS.OBJECT_DEPENDENCIES WHERE OBJECT_NAME = 'YOUR_VIEW_NAME' AND OBJECT_SCHEMA_NAME = 'YOUR_SCHEMA_NAME';6
Investigate any objects listed in the `REFERENCED_OBJECT_NAME` column. Ensure they are present and correctly spelled.
7
If an object is missing or incorrect, either recreate the missing object, correct the reference in the view definition, or update the object name.
8
Recompile the view after making corrections. In SAP HANA Studio, right-click the view and select 'Recompile'.
3. Address Authorization and Privilege Issues medium
Confirm that the user or application attempting to create or query the view has the necessary privileges on the underlying objects.
1
Identify the user or role that is executing the operation that leads to the error.
2
Determine which tables, views, or functions are being referenced in the view definition.
3
Check the privileges granted to the user/role on these underlying objects. The user needs at least `SELECT` privilege on all referenced tables/views.
4
Use the following SQL query to check privileges for a specific user on a specific object. Replace `USER_NAME`, `SCHEMA_NAME`, and `OBJECT_NAME`.
SELECT * FROM SYS.PRIVILEGES WHERE GRANTEE = 'USER_NAME' AND OBJECT_SCHEMA = 'SCHEMA_NAME' AND OBJECT_NAME = 'OBJECT_NAME';5
If privileges are missing, grant the necessary `SELECT` privilege. For example, to grant SELECT on a table to a user:
GRANT SELECT ON "SCHEMA_NAME"."TABLE_NAME" TO "USER_NAME";6
If the view itself is being created, the user needs `CREATE VIEW` privilege on the schema.
GRANT CREATE VIEW TO "USER_NAME";7
Ensure that the user has `USAGE` privilege on the schema where the view resides and on any schemas containing referenced objects.
GRANT USAGE ON SCHEMA "SCHEMA_NAME" TO "USER_NAME";8
After granting privileges, the user might need to re-log in for the changes to take effect.
