  The SAP error message 8B307 indicates that there is an issue with the surcharge rate and ICMS (Imposto sobre Circulação de Mercadorias e Serviços) rate being negative in the context of Brazilian tax calculations. This error typically arises in the context of billing or invoicing processes where tax calculations are performed.
  Cause:
  
  Negative Values: The error occurs when the system encounters a negative value for either the surcharge rate or the ICMS rate. In tax calculations, negative rates are generally not valid, as they imply a refund or discount that is not properly configured.
  Configuration Issues: There may be incorrect configuration in the tax settings or master data related to the customer, material, or pricing conditions.
  Data Entry Errors: Manual entry errors in the pricing conditions or tax codes can lead to negative values being entered inadvertently.
  Custom Logic: If there are custom developments or enhancements in the pricing logic, they might be incorrectly calculating the rates.
  
  Solution:
  
  
  Check Configuration: Review the configuration settings for tax codes and pricing conditions in the SAP system. Ensure that the surcharge and ICMS rates are set up correctly and do not have negative values.
  
  Transaction Codes: Use transaction codes like OB40 (for tax codes) and VK11 (for pricing conditions) to review and adjust settings.

  Analyze Pricing Conditions: Look into the pricing conditions applied to the sales document. Ensure that there are no discounts or surcharges that are incorrectly set to negative values.
  
  Transaction Code: Use VK13 to display pricing conditions.
  
  
  
  Check Custom Logic: If there are any custom developments or user exits that affect pricing or tax calculations, review the logic to ensure it is functioning as intended.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to tax calculations in Brazil for any specific guidelines or updates that may affect the configuration.
