This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools that require mapping of data from legacy systems to the new SAP system.
  Cause:
  The error occurs when:
  
  Missing Mapping Values: The mapping values that are required for the conversion process have not been defined in the system. This could be due to incomplete configuration or setup of the migration project.
  Incorrect Configuration: The mapping configuration might be incorrect or not aligned with the data being processed.

  Solution:
  To resolve the CNV_PE_S4120 error, you can follow these steps:
  
  
  Define Mapping Values:
  
  Go to the relevant transaction or configuration area where mapping values are defined (e.g., transaction code LTMC for the Migration Cockpit).

  Review Mapping Configuration:
  
  Ensure that the mapping configuration is correctly set up. This includes checking the source and target fields and ensuring that they are correctly aligned.
  If you are using a predefined template, ensure that it is correctly configured for your specific data migration scenario.
  
  
  
  Check Data Source:
  
  Verify that the source data contains the necessary values that can be mapped to the target system. If there are discrepancies, you may need to clean or transform the source data before migration.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or guides related to the specific migration tool you are using. This can provide insights into how to properly set up mapping values.
  
  
  
  Testing:
