  Solutions:
  
  Review Yield Curve Data: Check the yield curve data for the specified currency and ensure that all interest rates are entered correctly and logically.
  Correct Inconsistencies: Adjust the interest rates to ensure they follow a consistent pattern. For example, if rates are expected to increase, ensure that each subsequent rate is higher than the previous one.
  Fill Missing Entries: If there are missing interest rates for certain periods, add the necessary entries to complete the yield curve.
  Check Configuration: Verify the configuration settings for the yield curve in the SAP system to ensure they are set up correctly.
