  Go to the SAP Customizing Implementation Guide (IMG) and navigate to the relevant section for tax configuration.
  Ensure that the "Tax-from role" parameter is properly maintained in the decision tree. This may involve defining the roles and ensuring they are linked to the appropriate tax categories.
  
  
  
  Maintain Decision Tree:
  
  Access the decision tree configuration (Transaction code: OBYZ or similar, depending on your version).
  Verify that the decision tree includes the necessary entries for the "Tax-from role." If it is missing, you will need to add it.
  
  
  
  Review Tax Codes:
  
  Check the tax codes associated with the transaction to ensure they are correctly set up and linked to the decision tree.
