SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_PE_GEN - Messages for object generation

• Message number: 017

• Message text: Generation of object &1: Object already exists

What causes this issue?

Depending on the <DS:TX.CNV_PE_TX_GEN_MODE>generation mode</>, existing
objects may not be overwritten but remain unchanged.

System Response

This object was generated with generation mode &V2&.
In case this messages occurs in the context of the function group
generation, the meaning is that the function group is not deleted, as
this would also delete all function modules within the function group.
This might be unwanted in certain situations.
<ZH>Note</>
Independent of the generation mode, in case an object is generated the
very first time, the program checks if the object (name) is not yet
available in the system where the object shall be generated/created. In
case an object with the same name already exists, the generation process
will stop and nothing will be deleted or generated.

How to fix this error?

Consider the statements above.
In case of the generation of a new object (very first time), this
situation indicates a problem with the number range status in the
control system. To solve the problem, contact SAP for support.

• What is the cause and solution for SAP error message CNV_PE_GEN017 - Generation of object &1: Object already exists ?

  The SAP error message CNV_PE_GEN017 indicates that there is an attempt to generate an object (like a table, view, or other database object) that already exists in the system. This error typically occurs during data migration or conversion processes, especially when using SAP's Conversion Tools or during the execution of a migration project.
  Cause:
  
  
  Object Already Exists: The primary cause of this error is that the object you are trying to create already exists in the database. This can happen if:
  
  The migration process was run previously and the object was created.
  There was an incomplete or failed migration that left behind some objects.
  The object was manually created or modified outside of the migration process.
  
  
  
  Naming Conflicts: There may be naming conflicts if the same object name is used in different contexts or if there are multiple migration runs that attempt to create the same object.
  
  
  Solution:
  
  
  Check for Existing Objects: 
  
  Use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to check if the object already exists in the system.
  If the object exists and is not needed, you may consider deleting it or renaming it if it is safe to do so.
  
  
  
  Adjust Migration Settings: 
  
  Review the migration settings or parameters to ensure that the process is not trying to recreate existing objects.
  If the migration tool allows, you may be able to skip the creation of existing objects.
  
  
  
  Clean Up Before Migration: 
  
  Before running the migration again, ensure that the environment is clean. This may involve dropping existing objects that are no longer needed or ensuring that the migration process is idempotent (i.e., can be run multiple times without adverse effects).
  
  
  
  Consult Documentation: 
  
  Refer to the specific documentation for the migration tool or process you are using. There may be specific guidelines or best practices for handling existing objects.
  
  
  
  Error Handling in Scripts: 
  
  If you are using custom scripts or programs for migration, implement error handling to check for the existence of objects before attempting to create them.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to the specific migration tool you are using. There may be known issues or patches that address this error.
  Logs and Traces: Review logs and traces generated during the migration process for additional context on the error.
  SAP Community: Engage with the SAP Community or forums for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the CNV_PE_GEN017 error and successfully proceed with your migration or conversion process.
