  The SAP error message CNV_40301005 typically occurs during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error is related to account determination and indicates that the same value is being mapped multiple times, which can lead to ambiguity in the mapping process.
  Cause:
  The error arises when:
  
  The mapping of account determination values is not unique, meaning that the same value is being assigned to multiple entries in the mapping table.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Mapping Configuration:

  Adjust Mapping Rules:
  
  If necessary, adjust the mapping rules to ensure that they are correctly defined and do not lead to conflicts. This may involve creating new mappings or modifying existing ones.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for handling account determination mappings.
