  SAP Error Message:
  WHT_BR020: Origin of base can only be set to Nota fiscal with Modified tax amount
  
  Cause
  This error occurs in the context of Withholding Tax (WHT) processing in SAP, specifically when dealing with Brazilian tax requirements (Nota Fiscal). The message indicates that the "Origin of base" field in the withholding tax configuration or document is set incorrectly.
  
  The "Origin of base" field is used to specify the source of the tax base amount for withholding tax calculation.
  For the scenario where the tax amount has been modified manually (Modified tax amount), the system expects the origin of the base to be set to "Nota fiscal" (the official Brazilian tax document).
  If the origin is set to something else (e.g., Invoice, Document, or other), the system throws this error because it violates the Brazilian tax law or SAP's validation logic for withholding tax.
  
  
  When does this happen?
  
  During withholding tax calculation or posting in Brazil localization.
