Description

This error indicates that an identifier (such as a variable, parameter, or column alias) used within an SAP S/4HANA SQLScript procedure or function has not been properly declared or is out of scope. It typically occurs during compilation or execution of custom ABAP CDS views or stored procedures that leverage SQLScript.

Error Message

ERR_SQLSCRIPT_ID_NOT_DECLARED: Identifier must be declared

🔍

Known Causes

4 known causes

⚠️

Undeclared Variable or Parameter

A variable, constant, or parameter was used in the SQLScript code without being explicitly declared using `DECLARE` or being part of the procedure's signature.

⚠️

Typographical Error

The identifier was declared, but a misspelling occurred when referencing it later in the SQLScript code, leading the system to treat it as a new, undeclared identifier.

⚠️

Scope Mismatch

An identifier was declared in a different scope (e.g., inside a block or sub-procedure) and is being referenced outside its defined visibility, making it inaccessible.

⚠️

Missing Object Prefix

When referencing database objects like tables or views, the necessary schema or library prefix might be omitted, causing the system to not recognize the identifier in the current context.

Solutions

3 solutions available

1. Declare Missing SQLScript Identifiers easy

Explicitly declare all variables and parameters used within SQLScript procedures or functions.

1

Identify the SQLScript object (e.g., stored procedure, function) that is throwing the error.

2

Examine the SQLScript code for any variables or parameters that are used but not declared. This often happens with temporary tables, cursors, or local variables.

-- Example of an undeclared variable
-- SELECT my_variable FROM dual; -- my_variable is not declared

-- Corrected example with declaration
DECLARE my_variable INT;
SELECT 1 INTO my_variable FROM dual;
SELECT my_variable FROM dual;

3

Add DECLARE statements at the beginning of your SQLScript block for all such identifiers. Ensure the data type is correctly specified.

-- For a table variable:
DECLARE temp_table TABLE (
  column1 INT,
  column2 VARCHAR(100)
);

-- For a cursor:
DECLARE my_cursor CURSOR FOR SELECT column1 FROM my_table;

-- For a simple variable:
DECLARE counter INT DEFAULT 0;

4

Recompile and test the SQLScript object.

2. Verify Parameter and Variable Scope medium

Ensure that parameters and variables are declared in the correct scope and accessible where they are used.

1

Locate the SQLScript object causing the error.

2

Review the parameters passed into the procedure or function. Ensure they match the declared parameter list in terms of name and type.

-- Procedure definition
CREATE PROCEDURE my_procedure (IN p_input_param INT)
BEGIN
  -- ... use p_input_param ...
END;

-- Calling the procedure (ensure p_input_param is provided)
CALL my_procedure(10);

3

Check if any local variables are being used before their declaration or outside their defined block. SQLScript follows block-level scoping for declared variables.

-- Incorrect scope example
IF TRUE THEN
  DECLARE x INT;
  SET x = 5;
END IF;

-- SELECT x FROM dual; -- x is out of scope here

-- Correct scope example
DECLARE x INT;
IF TRUE THEN
  SET x = 5;
END IF;

SELECT x FROM dual; -- x is accessible here

4

If using nested procedures or functions, ensure that identifiers declared in an outer scope are not being redeclared or shadowed in an inner scope without proper handling.

5

Recompile and test the SQLScript object.

3. Review Generated SQL and System Objects advanced

Investigate if the error stems from SAP S/4HANA's internal SQL generation or a reference to a missing system object.

1

Identify the SAP S/4HANA application component or transaction that triggers the SQLScript error.

2

Use SAP's debugging tools (e.g., ST05 SQL Trace, SAT ABAP Trace) to capture the exact SQL statement being executed when the error occurs. Look for the SQLScript object name.

3

Analyze the captured SQL. If the error message points to an identifier, check if it's a system table, view, or function that might be missing or have a different name in your specific S/4HANA version or support package level.

-- Example: If the error is ERR_SQLSCRIPT_ID_NOT_DECLARED for 'MY_SYSTEM_VIEW'
-- Check if 'MY_SYSTEM_VIEW' exists in the database catalog.
-- SELECT table_name FROM views WHERE table_name = 'MY_SYSTEM_VIEW';

4

Consult SAP Notes relevant to the application component and the error code (1287). SAP often releases corrections for issues related to internal SQLScript objects.

5

If the issue appears to be within standard SAP code, consider raising an incident with SAP Support. They can provide guidance on specific system objects or patches.
