  The SAP error message CNV_CMIS_M015 indicates that a value already exists for a specific field in the context of a data migration or conversion process. This error typically arises during the execution of a data migration project, particularly when using the SAP Conversion Tools or during the data import process.
  Cause:
  
  
  Duplicate Values: The most common cause of this error is that the value being inserted or updated already exists in the target table for the specified field. This can happen if:
  
  The data being migrated contains duplicates.
  The target system already has existing records with the same value in the specified field.
  
  
  
  Data Integrity Constraints: The field may have unique constraints or primary key constraints that prevent duplicate entries.
  
  
  Incorrect Mapping: There may be an issue with how the data is mapped from the source to the target, leading to attempts to insert duplicate values.
  
  
  Solution:
  
  
  Identify Duplicates: Check the source data for duplicates. You can use tools like Excel or SQL queries to identify any duplicate values in the source dataset.
  
  
  Data Cleansing: Remove or modify duplicate entries in the source data before attempting the migration again. Ensure that each value in the field is unique.
  
  
  Check Existing Data: Review the target system to see if the value already exists. If it does, you may need to decide whether to update the existing record or skip the insertion of the duplicate.
  
  
  Adjust Mapping: If the mapping is incorrect, ensure that the data is being mapped correctly from the source to the target fields.
  
  
  Consult Documentation: Review the documentation for the specific migration tool or process you are using to ensure that you are following the correct procedures.
  
  
  Error Handling: Implement error handling in your migration process to log and manage such errors effectively, allowing for easier troubleshooting in the future.
