SAP S/4HANA Error 1354: SQLScript Cursor Not Opened
Description
This error indicates that an attempt was made to fetch data from a database cursor that has not been properly initialized or opened. It typically occurs within custom SQLScript procedures or views in SAP HANA when the `OPEN` statement for a cursor is missing or not executed before a `FETCH` operation.
Error Message
ERR_SQLSCRIPT_CURSOR_NOT_OPENED
Known Causes
3 known causesMissing OPEN Statement
The most common cause is omitting the `OPEN` statement for the cursor before attempting to `FETCH` data from it within your SQLScript code.
Conditional Cursor Opening
The `OPEN` statement for the cursor is placed within a conditional block (e.g., `IF` statement) that was not met, preventing the cursor from being opened.
Incorrect Cursor Scope or Name
Attempting to `FETCH` from a cursor that is either out of its defined scope or has been referenced with an incorrect name, leading to it being perceived as unopened.
Solutions
3 solutions available1. Verify Cursor Declaration and Usage in ABAP Programs medium
Ensure the cursor is properly declared and opened before use within ABAP SQL statements.
1
Identify the ABAP program that is triggering the error. This can often be found in the application log or ST22 dump.
2
Locate the section of the ABAP code that uses Open SQL or Native SQL with a cursor. Look for `OPEN CURSOR`, `FETCH NEXT CURSOR`, and `CLOSE CURSOR` statements.
3
Verify that the `OPEN CURSOR` statement is executed successfully *before* any attempt to `FETCH NEXT CURSOR` from that cursor.
DATA lv_cursor TYPE cursor.
OPEN CURSOR lv_cursor FOR SELECT ... FROM ... .
IF sy-subrc = 0.
FETCH NEXT CURSOR lv_cursor INTO ... .
CLOSE CURSOR lv_cursor.
ENDIF.4
Check for logical errors where a cursor might be implicitly closed or not opened due to conditional logic or exceptions. Ensure that all code paths leading to cursor usage correctly open the cursor.
5
If using Native SQL, ensure the database cursor is explicitly declared and opened using the appropriate database-specific syntax within the ABAP program.
2. Analyze SQLScript Procedures for Correct Cursor Handling advanced
Examine SQLScript procedures for proper cursor declaration, opening, fetching, and closing logic.
1
Identify the specific SQLScript procedure that is causing the error. This might be indicated in the application logs or ST22 dumps.
2
Open the SQLScript procedure in a database development tool (e.g., SAP HANA Studio, SAP Business Application Studio).
3
Look for cursor declarations using `DECLARE CURSOR`. Ensure that the cursor is declared with a valid SELECT statement.
DECLARE my_cursor CURSOR FOR SELECT col1, col2 FROM my_table WHERE condition;
4
Verify that the cursor is opened *before* any `FETCH` operations are attempted. This is typically done implicitly when the cursor is declared in some contexts, but explicit opening might be required in others or if the cursor is declared separately.
5
Check the loop structure (e.g., `LOOP AT ... FROM CURSOR`) to ensure it correctly iterates through the cursor rows. Ensure the loop condition is valid and the cursor is not already exhausted.
LOOP AT my_cursor INTO wa_row_data.
-- Process row
ENDLOOP.6
Confirm that the cursor is properly closed, especially if it's not managed by a loop that implicitly closes it upon completion. Use `CLOSE CURSOR my_cursor;` if necessary.
CLOSE CURSOR my_cursor;
7
Review any exception handling within the SQLScript procedure. Ensure that if an error occurs during cursor operations, the cursor is still properly managed (e.g., closed) to prevent subsequent errors.
3. Review Database Connection and Transaction Management medium
Ensure the database connection remains valid and transactions are managed correctly.
1
Investigate if the error occurs intermittently. This could point to issues with database connection timeouts or transaction rollbacks.
2
Check SAP Gateway or application server logs for any database connection errors or network interruptions that might have occurred prior to the error.
3
In the context of ABAP, ensure that database cursors are not being used across separate, committed, or rolled-back transactions. A cursor is typically tied to the current transaction context.
4
For direct database access scenarios (less common in S/4HANA for transactional data, but possible for analytical purposes), ensure that the connection is properly established and maintained throughout the cursor's lifecycle.
5
If you suspect connection pooling issues, consult with your SAP Basis team to review the database connection configuration and health.
