• What is the cause and solution for SAP error message CNV20201037 - Found no. level is lower! Subobj &1,NoRg &2, extern.= &3: ?

  The SAP error message CNV20201037 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 mismatch in the expected hierarchy or level of data being processed. Specifically, it suggests that the found number level is lower than what is required for the specified sub-object.
  Cause:
  
  Data Hierarchy Mismatch: The error usually arises when the data being migrated does not conform to the expected hierarchy or structure defined in the target system. For example, if the migration process expects a certain level of detail (like a higher-level category) but receives a lower-level detail (like a sub-category), this error can occur.
  Incorrect Mapping: There may be an issue with how the source data is mapped to the target structure. If the mapping does not align with the expected levels, this error can be triggered.
  Missing Data: If certain required data elements are missing or not populated correctly in the source data, it can lead to this error.
  
  Solution:
  
  Check Data Hierarchy: Review the data being migrated to ensure that it adheres to the expected hierarchy. Make sure that the levels of data in the source match what is required in the target system.
  Review Mapping Configuration: Verify the mapping configuration in the migration tool. Ensure that the source fields are correctly mapped to the target fields and that the levels correspond appropriately.
  Data Validation: Perform a validation of the source data to identify any missing or incorrectly structured records. Correct any discrepancies before attempting the migration again.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or requirements for the data structure that need to be followed.
  Error Logs: Check the detailed error logs for additional context on the error. This can provide insights into which specific records or fields are causing the issue.
