SAP S/4HANA Error 2864: Invalid SQLScript Table Type

Identify the SQLScript that is failing. This could be a stored procedure, function, or a direct SQLScript execution.

Examine the SQLScript code and locate where a table type is being declared or used. Look for keywords like `TABLE`, `TYPE`, or explicit table type names.

Compare the table type name used in the SQLScript with the actual available table types in your SAP HANA database. You can query the system views for this.

Execute the following SQL query to list all defined table types in your schema. Replace 'YOUR_SCHEMA_NAME' with the actual schema where the table type should exist.

SELECT * FROM SYS.TABLE_TYPES WHERE SCHEMA_NAME = 'YOUR_SCHEMA_NAME';

If the table type is missing or misspelled in the SQLScript, correct it to match an existing and valid table type. If the table type needs to be created, refer to Solution 2.

Determine the exact structure (column names and data types) of the table type required by the failing SQLScript.

If the table type does not exist, you will need to create it. Execute a `CREATE TYPE` statement in SAP HANA Studio or another SQL client.

Example of creating a table type. Replace `MY_TABLE_TYPE` with your desired type name and adjust the column definitions as needed.

CREATE TYPE MY_TABLE_TYPE AS TABLE (
  COLUMN1 VARCHAR(100),
  COLUMN2 INTEGER,
  COLUMN3 DECIMAL(10,2)
);

If the table type exists but is corrupted or has an incorrect definition, you might need to drop and recreate it. **Caution:** Dropping a type can impact other objects that use it. Ensure you understand the dependencies before proceeding.

To drop an existing table type (use with extreme caution):

DROP TYPE MY_TABLE_TYPE;

After creating or recreating the table type, re-execute the SQLScript to verify the error is resolved.

SAP HANA's case sensitivity for object names can be configured. Ensure the case of the table type name in your SQLScript exactly matches its definition in the database.

If your SQLScript is not in the same schema where the table type is defined, explicitly qualify the table type name with the schema name.

For example, if your table type `MY_TABLE_TYPE` is in schema `SCHEMA_A` and your SQLScript is in `SCHEMA_B`, you should refer to it as `SCHEMA_A.MY_TABLE_TYPE` within the SQLScript.

Verify the current schema context of your SQLScript. If it's running in a context where the table type is not visible, this can cause the error. You can set the schema context using `SET SCHEMA 'YOUR_SCHEMA_NAME';` before executing the script, or ensure the table type is in the default schema or a schema that is in the search path.

Locate the stored procedure or function definition that is causing the error.

Examine the parameter list of the procedure or function. Identify any parameters that are declared with a table type.

Verify that the declared table type for each parameter is valid and exists in the database, following the steps in Solution 1.

Ensure that the data types and structure of the table type used for the parameter definition in the procedure/function signature exactly match the definition of the actual table type object in the database.

If you are calling this procedure/function from another SQLScript or application, ensure that the data structure being passed for the table type parameter conforms to the defined table type. Mismatches in column count, names, or data types can also indirectly lead to this error if the system attempts to validate the passed data against an invalid type definition.
