SAP S/4HANA Error 2847: Incorrect Table Type in SQLScript Parameter
Description
This error signifies that an SQLScript procedure or function in SAP HANA received an input parameter that does not conform to its expected table type definition. It typically occurs when the structure (column names, data types, order) of the provided table or view does not match the type declared for the parameter.
Error Message
ERR_SQLSCRIPT_PARAM_WRONG_TABLE_TYPE
Known Causes
4 known causesMismatched Column Definitions
The input table or view passed to the SQLScript parameter has columns with different names, data types, or order than those defined in the expected table type.
Incorrect Table Type Reference
The SQLScript procedure or function is called with a table or view that belongs to a different, incompatible table type than what the parameter was explicitly defined to accept.
Missing Required Columns
The table or view provided as a parameter is missing one or more essential columns that are part of the SQLScript parameter's defined table type.
Data Type Incompatibility
Even if column names match, the data types of corresponding columns in the input table and the defined table type are incompatible (e.g., passing a string where an integer is expected).
Solutions
3 solutions available1. Verify SQLScript Table Type Parameter Declaration medium
Ensure the table type declared for a parameter in your SQLScript matches the actual table type being passed.
1
Identify the SQLScript procedure or function causing the error. This is usually evident from the call stack or the surrounding code where the error occurs.
2
Examine the parameter declaration within the SQLScript definition. Look for parameters declared with a table type (e.g., TABLE, TT_MY_TABLE).
PROCEDURE my_procedure (IN input_table TT_MY_TABLE, OUT output_table TT_OTHER_TABLE) AS ...3
Compare the declared table type (e.g., TT_MY_TABLE) with the actual table type of the variable or table being passed to this parameter during the procedure/function call.
CALL my_procedure(:my_data_table, :results); -- Ensure TYPE(my_data_table) matches TT_MY_TABLE4
If there's a mismatch, correct either the parameter declaration in the SQLScript or the type of the variable being passed to align them.
e.g., If 'my_data_table' is of type TT_ANOTHER_TABLE, either change the declaration to TT_ANOTHER_TABLE or ensure the data passed is compatible with TT_MY_TABLE.2. Check Host Variable Table Type in ABAP or Calling Program medium
Confirm that the host variable (e.g., an ABAP internal table) used to pass data to an SQLScript has the correct structure and type.
1
Locate the ABAP program or other calling application that invokes the SQLScript procedure or function.
2
Identify the host variable (often an internal table in ABAP) that is being passed as a table parameter to the SQLScript.
DATA lt_my_data TYPE tt_my_table.3
Verify that the TYPE declaration of this host variable in the calling program precisely matches the table type expected by the SQLScript parameter. This includes field names, data types, and lengths.
e.g., If SQLScript expects TT_MY_TABLE with fields COL1 (VARCHAR(10)) and COL2 (INT), ensure lt_my_data in ABAP is declared identically.4
If the host variable's type is incorrect, redefine it to match the SQLScript's expected table type.
e.g., RE DEFINE tt_my_table AS ... (matching SQLScript definition)3. Recreate SQLScript Table Type Definition advanced
In rare cases, the SQLScript's table type definition might be corrupted or out of sync. Recreating it can resolve the issue.
1
Identify the specific table type used in the SQLScript parameter that is causing the error.
2
Back up the existing table type definition. You can do this by exporting it or by copying its definition from the database.
SELECT definition FROM sys.types WHERE type_name = 'TT_MY_TABLE';3
Drop the existing table type. **Caution: This will impact any SQLScripts or other database objects that rely on this table type. Ensure you have a rollback plan.**
DROP TYPE TT_MY_TABLE;4
Recreate the table type using the backed-up definition or by re-entering the correct structure.
CREATE TYPE TT_MY_TABLE AS TABLE (col1 VARCHAR(10), col2 INT);5
Recompile or re-execute the SQLScript that was failing to ensure it now uses the recreated table type correctly.
