• What is the cause and solution for SAP error message CNV20600065 - Company code & exists more than once as target; no 1:1 rename! ?

  The SAP error message CNV20600065 indicates that there is a conflict in the data migration process, specifically related to the company code mapping during a conversion or migration project. This error occurs when the target company code you are trying to map already exists more than once in the target system, which prevents a one-to-one mapping (rename) from the source to the target.
  Cause:
  
  Duplicate Company Codes: The target system has multiple entries for the same company code, which can happen if there are multiple instances of the same company code in the source data or if the target system has been incorrectly set up.
  Incorrect Mapping: The mapping configuration in the migration tool may not be set up correctly, leading to multiple source company codes trying to map to the same target company code.
  Data Integrity Issues: There may be issues with the integrity of the data being migrated, such as duplicates in the source data.
  
  Solution:
  
  Check Target Company Codes: Review the target system to identify if the company code exists more than once. You can do this by checking the configuration in the target system (transaction code OX02 for company codes).
  Adjust Mapping: If you find that the company code is indeed duplicated, you will need to adjust the mapping in the migration tool to ensure that each source company code maps to a unique target company code.
  Data Cleanup: If the duplicates are found in the source data, you may need to clean up the source data to ensure that each company code is unique before attempting the migration again.
  Consult Documentation: Refer to the specific documentation for the migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Landscape Transformation) for detailed instructions on how to handle company code mappings.
  Testing: After making the necessary adjustments, perform a test migration to ensure that the issue is resolved before proceeding with the full migration.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OX02 (for company code configuration) and other related tools for data migration.
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address known issues.
  Migration Tools: Understand the specific migration tool you are using, as different tools may have different methods for handling company code mappings.

  By addressing the root cause of the duplicate company codes and ensuring proper mapping, you should be able to resolve the CNV20600065 error and proceed with your migration successfully.
