• What is the cause and solution for SAP error message CNV_20211_CHECK142 - No implicit merges due to mapping of companies ?

  The SAP error message CNV_20211_CHECK142 typically occurs during data migration processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there are issues with the mapping of companies, which prevents implicit merges from occurring.
  Cause:
  The error is generally caused by one or more of the following reasons:
  
  
  Inconsistent Company Code Mapping: The mapping of company codes in the source and target systems may not be consistent. This can happen if the same company code exists in both systems but is mapped differently.
  
  
  Missing Company Code: The target system may not have the necessary company codes defined that are required for the migration.
  
  
  Data Integrity Issues: There may be data integrity issues in the source data that prevent the system from merging records as expected.
  
  
  Configuration Issues: The configuration settings in the migration tool may not be set up correctly, leading to issues with how companies are mapped.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Review Company Code Mapping:
  
  Check the mapping of company codes in the migration tool. Ensure that each source company code is correctly mapped to a target company code.
  Make sure that there are no duplicate mappings or inconsistencies.
  
  
  
  Define Missing Company Codes:
  
  If any company codes are missing in the target system, create them in the target system before running the migration again.
  
  
  
  Data Cleansing:
  
  Review the source data for any inconsistencies or errors that may affect the migration. Cleanse the data as necessary to ensure it meets the requirements for migration.
  
  
  
  Check Configuration Settings:
  
  Verify the configuration settings in the migration tool to ensure they are set up correctly for your specific migration scenario.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the migration process for any specific guidelines or requirements regarding company code mapping.
