  Review Tax Configuration: Check the configuration settings for tax codes and tax classes in the SAP system. Ensure that all necessary tax classes are defined and that their validity periods are correctly set.
  Consult with Tax Experts: If there are changes in tax regulations, consult with your finance or tax department to ensure compliance and correct configuration in SAP.
  Transaction Date: If possible, adjust the transaction date to a period where the tax class is valid.
