SAP S/4HANA Error 329: Duplicate Function/Procedure Name
Description
This error indicates an attempt to create a database function or procedure with a name that already exists within the current schema or scope. It commonly occurs during development, customization, or deployment activities when a new object's name conflicts with an existing one.
Error Message
ERR_SQL_EXST_FUNC_PROC: Cannot use duplicate name of function or procedure
Known Causes
4 known causesManual Name Duplication
A user manually entered a name for a new function or procedure that is already in use within the database schema.
Automated Script Conflict
An automated script or deployment process attempted to create a database object with a name already in use, without prior existence checks.
Schema Naming Collision
The function or procedure name already exists within the specified database schema or scope where the creation is attempted.
Incomplete Object Deletion
An object with the same name was not properly dropped or cleaned up before a new creation attempt was made during a redeployment.
Solutions
3 solutions available1. Rename Conflicting Function or Procedure medium
Identify and rename the duplicate function or procedure to resolve the naming conflict.
1
Identify the exact name of the function or procedure causing the conflict. This is usually provided in the error message or logs.
2
Connect to your SAP HANA database using a suitable client tool (e.g., SAP HANA Studio, hdbsql, or a SQL client that supports HANA).
3
Query the system views to find existing functions and procedures with the same name. Replace 'DUPLICATE_NAME' with the actual name found in the error message.
SELECT SCHEMA_NAME, OBJECT_NAME, OBJECT_TYPE FROM SYS.OBJECTS WHERE OBJECT_NAME = 'DUPLICATE_NAME';4
Once the duplicate is identified, determine which object is the intended one and which needs to be renamed. This might involve checking creation dates, associated applications, or documentation.
5
Rename the duplicate function or procedure. You will need appropriate privileges (e.g., ALTER privilege on the schema or object). Replace 'OLD_NAME' with the duplicate name and 'NEW_NAME' with a unique name.
RENAME OBJECT 'SCHEMA_NAME'.'OLD_NAME' TO 'NEW_NAME';6
If the duplicate is a function and the other is a procedure (or vice-versa) with the same name, the error might still occur if the system treats them as conflicting identifiers in certain contexts. Renaming one of them is still the recommended approach.
7
Re-run the operation that triggered the error to confirm the issue is resolved.
2. Review and Consolidate Database Objects advanced
Thoroughly examine your database schema for redundant or incorrectly created functions and procedures.
1
Perform a comprehensive audit of your SAP HANA database schema. Focus on stored procedures and functions, especially those created by custom developments or during upgrades/migrations.
2
Use SQL queries to list all functions and procedures, grouping them by name to identify potential duplicates. Consider different schemas.
SELECT SCHEMA_NAME, OBJECT_NAME, COUNT(*) FROM SYS.OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION', 'PROCEDURE') GROUP BY SCHEMA_NAME, OBJECT_NAME HAVING COUNT(*) > 1;3
For each identified duplicate name, investigate the purpose and implementation of each object. This may involve reviewing the source code of the functions/procedures.
SELECT SCHEMA_NAME, OBJECT_NAME, DEFINITION FROM SYS.OBJECT_DEPENDENCIES WHERE OBJECT_NAME = 'DUPLICATE_NAME';4
If you find genuinely redundant objects (e.g., multiple versions of the same logic), decide on a single, definitive version to keep. This might involve refactoring the code into a single, robust object.
5
Drop the redundant functions or procedures after ensuring no critical processes depend on them. **Exercise extreme caution when dropping objects.**
DROP FUNCTION 'SCHEMA_NAME'.'REDUNDANT_OBJECT_NAME';6
Document the consolidation process and the remaining, unique objects.
7
Test all affected applications and processes to ensure they function correctly with the consolidated objects.
3. Check for Case Sensitivity Issues easy
Verify if the duplicate name arises from case sensitivity differences in object naming.
1
Understand that SAP HANA object names are typically case-sensitive. The error might occur if you have, for example, a function named `MyFunction` and another named `myfunction` in the same schema.
2
When querying system views or issuing commands, be mindful of the exact casing of the object names.
3
Use a query that explicitly checks for both upper and lower case variations if you suspect a case sensitivity issue. Replace 'DUPLICATE_NAME' with the name as it appears in the error, but be aware of potential variations.
SELECT SCHEMA_NAME, OBJECT_NAME, OBJECT_TYPE FROM SYS.OBJECTS WHERE LOWER(OBJECT_NAME) = LOWER('DUPLICATE_NAME');4
If multiple objects are found with the same name but different casing, you will need to rename one of them to ensure a unique, consistently cased name. Follow the steps in 'Rename Conflicting Function or Procedure'.
