• What is the cause and solution for SAP error message CNV_20211_CHECK160 - No temporary duplicates are possible due to the mapping of companies ?

  The SAP error message CNV_20211_CHECK160 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there are issues with the mapping of companies, which prevents the creation of temporary duplicates in the target system.
  Cause:
  The error is generally caused by one of the following reasons:
  
  
  Company Code Mapping Issues: The mapping of company codes between the source and target systems is not correctly defined. This can happen if the same company code is being mapped to multiple entries or if there are inconsistencies in the mapping configuration.
  
  
  Duplicate Entries: The system has detected potential duplicate entries based on the mapping rules defined. This can occur if the same company code is being used for different entities or if there are overlaps in the data being migrated.
  
  
  Configuration Errors: There may be configuration errors in the migration settings that prevent the system from recognizing how to handle the company codes during the migration process.
  
  
  Solution:
  To resolve the CNV_20211_CHECK160 error, you can follow these steps:
  
  
  Review Company Code Mapping:
  
  Go to the mapping configuration in the migration tool.
  Ensure that each source company code is mapped to a unique target company code.
  Check for any duplicate mappings or inconsistencies.
  
  
  
  Check for Duplicates:
  
  Review the source data for any duplicate entries that may conflict with the mapping.
  Clean up the source data to ensure that there are no duplicates before attempting the migration again.
  
  
  
  Adjust Migration Settings:
  
  If applicable, adjust the settings in the migration cockpit to allow for temporary duplicates, if that is a valid approach for your migration strategy.
  Ensure that the migration settings align with the business requirements and data structure.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the specific migration tool you are using. There may be additional guidelines or best practices for handling company code mappings.
  
  
  
  Testing:
