• What is the cause and solution for SAP error message CNV20200118 - Target object &1=&2 exists, but is not the reference object! ?

  The SAP error message CNV20200118 indicates that there is a conflict with the target object during a data migration or conversion process. Specifically, it means that the target object (identified by &1 and &2) already exists in the system, but it does not match the expected reference object. This can occur during data migration scenarios, especially when using SAP's data migration tools or during system conversions.
  Cause:
  
  Existing Data Conflict: The target object already exists in the database, but its structure or attributes do not match the expected reference object that the migration process is trying to use.
  Incorrect Mapping: There may be an issue with how the data is being mapped from the source to the target, leading to inconsistencies.
  Data Integrity Issues: The existing data may have been altered or corrupted, leading to discrepancies with the reference object.
  Configuration Issues: The configuration settings for the migration process may not align with the current state of the target system.
  
  Solution:
  
  Check Existing Data: Investigate the existing target object to understand its structure and attributes. Compare it with the reference object to identify discrepancies.
  Data Cleanup: If the existing data is not needed, consider deleting or archiving it before running the migration again. Ensure that this action does not violate any data integrity or compliance requirements.
  Adjust Mapping: Review the mapping configuration in the migration tool to ensure that it aligns correctly with the target structure.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand the expected structure and any prerequisites.
  Use Transaction Codes: Utilize relevant transaction codes (like SE11 for data dictionary objects) to analyze the structure of the target object.
  Testing: Before running the migration in a production environment, conduct tests in a development or quality assurance environment to ensure that the migration process works as expected.
