Description

Error 383, 'ERR_SQL_INV_IDENTIFIER', signifies that a database object name (such as a table, column, or view) within an SQL statement is not recognized or cannot be found. This error frequently arises in custom reports, data migration scripts, or integrations interacting directly with the SAP S/4HANA database.

Known Causes

4 known causes

⚠️

Typographical Error

A common cause is a simple spelling mistake, incorrect casing, or an extra character in the name of a table, column, or other database object.

⚠️

Non-Existent Database Object

The referenced table, view, column, or other identifier genuinely does not exist in the database or the specified schema.

⚠️

Incorrect Schema or Context

The SQL statement is being executed against the wrong database schema or context where the identifier is not available or lacks proper qualification.

⚠️

Reserved Keyword Usage

An identifier used in the SQL statement might be a database reserved keyword, leading to misinterpretation by the SQL parser.

1. Correct Invalid Characters in SQL Identifiers easy

Removes or replaces invalid characters from table, column, or view names.

1

Identify the specific SQL identifier causing the error. This could be a table name, column name, view name, or any other object name used in your SQL statement.

ERR_SQL_INV_IDENTIFIER

2

Review the SAP S/4HANA naming conventions for SQL identifiers. Generally, these should start with a letter and can contain letters, numbers, and underscores (_). Avoid special characters, spaces, and reserved keywords.

Refer to SAP Notes like [1608303 - SQL naming conventions in SAP HANA] for detailed guidelines.

3

Modify the SQL statement to use a valid identifier. If the invalid character is part of a custom object, consider renaming the object in the database schema to comply with the rules. If it's an issue with a generated statement, investigate the source of the generation.

Example: If a table is named `MY-TABLE`, change it to `MY_TABLE` or `MYTABLE`.

4

If the invalid identifier is from an SAP standard object that has been unexpectedly modified or is being referenced incorrectly, consult SAP Notes for potential corrections or report an incident to SAP Support.

2. Check for Reserved Keywords Usage medium

Ensures SQL reserved keywords are not used as object names.

1

Examine the SQL statement and the names of all database objects (tables, columns, views, etc.) being referenced. Pay close attention to names that might be standard SQL reserved keywords.

Common SQL keywords include: SELECT, FROM, WHERE, INSERT, UPDATE, DELETE, CREATE, ALTER, DROP, TABLE, COLUMN, VIEW, INDEX, JOIN, GROUP, ORDER, BY, NULL, TRUE, FALSE, AS, IS, NOT, AND, OR, BETWEEN, LIKE, IN, EXISTS, ANY, ALL, CASE, WHEN, THEN, ELSE, END, DISTINCT, UNION, INTERSEVER, LIMIT, OFFSET, etc.

2

If a reserved keyword is being used as an identifier, it must be enclosed in double quotes (e.g., `"SELECT"`). However, it's strongly recommended to rename the object to avoid such conflicts, as quoted identifiers can sometimes lead to portability issues and are less readable.

Example: If a column is named `ORDER` (which is a reserved keyword), you might need to query it as `SELECT "ORDER" FROM MY_TABLE;`. A better solution is to rename the column to `ORDER_NUMBER` or similar.

3

For custom objects, rename the object in the database schema to a non-reserved keyword. For standard SAP objects, investigate if there's a known issue or a specific SAP Note addressing this.

3. Validate Table and Column Names in ABAP/CDS Views medium

Verifies object names in ABAP code or CDS views against the actual database schema.

1

If the error originates from an ABAP program or a CDS view, review the Data Dictionary (SE11) or the CDS source code for the table and column names being accessed.

N/A

2

Compare these names against the actual table and column names in the SAP S/4HANA database. This can be done using tools like the SAP HANA Studio or by querying the system catalog views.

Example Query (SAP HANA): SELECT table_name, column_name FROM "SYS"."COLUMNS" WHERE schema_name = 'SAPSR3' AND (table_name LIKE '%YOUR_TABLE%' OR column_name LIKE '%YOUR_COLUMN%');

3

Correct any discrepancies in the ABAP code or CDS view definition. Ensure that the casing and spelling of the identifiers precisely match the database schema.

Example: If SE11 shows table `MARA` but the ABAP code uses `MARA_CUSTOM`, correct the ABAP code to `MARA` (assuming `MARA` is the correct database object).

4

After making corrections, activate the ABAP program or re-activate the CDS view and re-test the functionality.
