• What is the cause and solution for SAP error message FF787 - Tax does not equal 0 when tax percentage rate is zero ?

  The SAP error message FF787 ("Tax does not equal 0 when tax percentage rate is zero") typically occurs during the processing of financial documents, such as invoices or payment transactions, when the system detects a discrepancy between the tax amount and the tax percentage rate. Specifically, this error indicates that there is a non-zero tax amount while the tax percentage rate is set to zero, which is logically inconsistent.
  Cause:
  
  Incorrect Tax Configuration: The tax code used in the transaction may be incorrectly configured, leading to a situation where the system expects no tax (0% rate) but finds a tax amount.
  Manual Entry Errors: Users may have manually entered a tax amount without realizing that the tax rate is set to zero.
  Data Migration Issues: If data was migrated from another system, there may be inconsistencies in how tax amounts and rates were transferred.
  Customizations or User Exits: Custom code or user exits may inadvertently alter tax calculations, leading to this error.
  
  Solution:
  
  
  Check Tax Code Configuration:
  
  Go to the transaction code OBYZ (or similar) to review the tax code settings.
  Ensure that the tax code is correctly configured with the appropriate tax percentage and that it aligns with the expected tax treatment for the transaction.
  
  
  
  Review Document Entries:
  
  Check the document that triggered the error. Look for any manual entries of tax amounts that do not correspond with the tax rate.
  If the tax amount is entered manually, consider removing it or adjusting the tax rate accordingly.
  
  
  
  Adjust Tax Amount:
  
  If the tax percentage is indeed supposed to be zero, ensure that the tax amount is also set to zero in the document.
  
  
  
  Consult with Finance Team:
  
  If unsure about the correct tax treatment, consult with your finance or tax compliance team to ensure that the tax codes and amounts are being applied correctly.
  
  
  
  Testing and Validation:
  
  After making changes, test the transaction again to ensure that the error does not recur.
  
  
  
  Check for Custom Code:
  
  If there are any custom developments or user exits that might affect tax calculations, review them to ensure they are functioning as intended.
