  The SAP error message CNV_12000018 typically indicates that there is an issue with saving changed rows during a data migration or conversion process. This error is often encountered in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  The error can be caused by several factors, including:
  
  Locking Issues: The rows you are trying to save may be locked by another process or user, preventing your changes from being committed.
  Data Integrity Violations: The data being saved may violate integrity constraints, such as foreign key constraints, unique constraints, or other business rules defined in the database.
  Technical Errors: There may be technical issues such as database connectivity problems, insufficient permissions, or issues with the underlying data model.
  Incomplete Data: Required fields may be missing or incorrectly formatted, leading to a failure when attempting to save the changes.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check for Locks: Use transaction codes like SM12 to check for any locks on the database tables you are trying to modify. If you find locks, you may need to wait for the other processes to complete or resolve the locks.
  
  
  Review Data: Ensure that the data you are trying to save meets all integrity constraints. Check for missing required fields, incorrect data types, or any other validation rules that may apply.
  
  
  Check Logs: Review the application logs (transaction SLG1) for more detailed error messages that can provide insights into what went wrong during the save operation.
  
  
  Permissions: Ensure that the user executing the migration has the necessary permissions to modify the data in the relevant tables.
  
  
  Retry the Operation: Sometimes, simply retrying the operation after addressing any identified issues can resolve the error.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for any additional troubleshooting steps or known issues.
  
  
  Contact SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP Support for further assistance, providing them with detailed information about the error and the context in which it occurred.
