• What is the cause and solution for SAP error message CNV_20000090 - Inverse fiscal year & not possible ?

  The SAP error message CNV_20000090 typically occurs during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is an issue with the fiscal year settings in the system, specifically that the fiscal year is set to an inverse or non-standard configuration, which is not supported for the migration process.
  Cause:
  
  Inverse Fiscal Year Configuration: The fiscal year variant in the system is configured in a way that does not align with the expected standard fiscal year settings. This can happen if the fiscal year is set to a non-standard configuration, such as a non-calendar year or if the fiscal year is defined in a way that does not follow the typical sequence.
  Data Inconsistencies: There may be inconsistencies in the data being migrated, such as periods that do not match the defined fiscal year settings.
  Migration Settings: The migration settings may not be correctly aligned with the fiscal year settings in the target system.
  
  Solution:
  
  
  Check Fiscal Year Variant: Review the fiscal year variant settings in the source and target systems. Ensure that they are configured correctly and consistently. You can do this by navigating to the following path in SAP:
  
  SPRO > Financial Accounting > Financial Accounting Global Settings > Fiscal Year > Define Fiscal Year Variant
  
  
  
  Adjust Fiscal Year Settings: If the fiscal year is indeed set to an inverse configuration, consider adjusting it to a standard fiscal year configuration. This may involve changing the fiscal year variant or creating a new one that aligns with the expected configuration.
  
  
  Data Validation: Validate the data being migrated to ensure that it adheres to the fiscal year settings. This may involve checking for any periods or entries that fall outside the defined fiscal year.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be additional guidelines or prerequisites that need to be followed to avoid this error.
  
  
  Testing: After making the necessary adjustments, perform a test migration to ensure that the error does not occur again.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific system configuration and migration scenario.
