  The SAP error message CNV20200151 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 is a conflict or inconsistency in the data being processed, specifically related to company codes (CoCd) and the values being migrated.
  Cause:
  The error message CNV20200151 is triggered when there is an attempt to change a value in a field that is not allowed or when the new value conflicts with existing data or business rules. The placeholders in the message represent:
  
  &1: The company code (CoCd) where the error occurred.
  &2: The old value that is currently in the system.
  &3: The new value that is being attempted to be set.
  
  This can happen due to various reasons, such as:
  
  Data integrity issues where the new value does not comply with the expected format or constraints.
  Business rules that prevent certain changes to specific fields.

  Adjust the New Value: If the new value is incorrect or not allowed, consider adjusting it to a valid value that complies with the business rules.
  
  
  Test in a Development Environment: If possible, replicate the migration process in a development or test environment to identify the root cause of the issue without affecting production data.
