• What is the cause and solution for SAP error message RQ321 - Interest equals 0, posting not possible ?

  The SAP error message RQ321, which states "Interest equals 0, posting not possible," typically occurs in the context of financial transactions, particularly when dealing with interest calculations in accounts receivable or payable. This error indicates that the system has determined that there is no interest to be posted for a particular transaction, which can prevent the posting from being completed.
  Causes:
  
  
  Zero Interest Calculation: The most common cause is that the interest calculation for the transaction has resulted in a value of zero. This can happen if:
  
  The interest rate is set to zero.
  The amount on which interest is calculated is zero.
  The interest calculation period does not cover any days (e.g., if the due date is the same as the posting date).
  
  
  
  Configuration Issues: There may be issues with the configuration of the interest calculation settings in the system. This includes settings related to interest calculation methods, rates, or periods.
  
  
  Transaction Data: The specific transaction data may not meet the criteria for interest calculation, leading to a zero interest amount.
  
  
  Solutions:
  
  
  Check Interest Calculation Settings:
  
  Review the interest calculation settings in the relevant configuration (e.g., in the Financial Accounting module).
  Ensure that the interest rates and calculation methods are correctly defined.
  
  
  
  Review Transaction Data:
  
  Check the specific transaction that is causing the error. Ensure that the amounts and dates are correctly entered and that they meet the criteria for interest calculation.
  If applicable, verify that the due date is set correctly and that there are no discrepancies in the transaction data.
  
  
  
  Adjust Interest Parameters:
  
  If the interest is expected to be calculated, ensure that the parameters (like interest rate and calculation period) are set correctly to allow for a non-zero interest amount.
  
  
  
  Manual Posting:
  
  If the transaction is valid but the system does not allow posting due to zero interest, consider manually adjusting the transaction or posting the necessary entries to reflect the correct interest amount.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on interest calculation and posting errors.
  
  
  
  Contact Support:
  
  If the issue persists after checking the above points, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FBL1N (Vendor Line Item Display), FBL5N (Customer Line Item Display), and others that may help in reviewing the transactions.
  SAP Notes: Check for any SAP Notes related to this error message, as they may provide additional insights or patches that could resolve the issue.
  User Exits and BAdIs: If custom logic is implemented in your SAP system, review any user exits or BAdIs that may affect interest calculations.
