• What is the cause and solution for SAP error message FICUSTOM066 - Interest calculation data is deleted when amounts are changed ?

  The SAP error message FICUSTOM066 indicates that interest calculation data has been deleted due to changes made to amounts in the relevant financial documents. This typically occurs in the context of financial transactions where interest calculations are based on specific amounts, and any modification to those amounts can invalidate the previously calculated interest data.
  Cause:
  
  Amount Changes: The primary cause of this error is the modification of amounts in financial documents (e.g., invoices, payments) that are linked to interest calculations.
  Interest Calculation Logic: The system is designed to recalculate interest based on the current amounts. If the amounts change, the previous interest calculation becomes irrelevant, leading to the deletion of the old interest data.
  Configuration Settings: Certain configuration settings in the SAP system may dictate how interest calculations are handled, including when and how data is deleted or recalculated.
  
  Solution:
  
  Review Changes: Check the changes made to the amounts in the financial documents. If the changes are necessary, ensure that you understand the implications for interest calculations.
  Recalculate Interest: After making changes to the amounts, you may need to manually trigger a recalculation of interest. This can often be done through specific transaction codes or reports in SAP that handle interest calculations.
  Check Configuration: Review the configuration settings related to interest calculation in your SAP system. Ensure that they align with your business requirements and that they are set up to handle changes appropriately.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling interest calculations and related error messages.
  Testing: If possible, test the changes in a development or quality assurance environment before applying them in production to ensure that the error does not recur.
  
  Related Information:

  SAP Notes: Check for any SAP Notes related to FICUSTOM066 for additional insights or patches that may address this issue.
