• What is the cause and solution for SAP error message FTYC026 - Yield curve &1 in &2 has ref. interest rates with the same maturity date ?

  The SAP error message FTYC026 indicates that there is an issue with the yield curve configuration in the system. Specifically, it means that there are reference interest rates with the same maturity date in the yield curve you are trying to use. This can lead to ambiguity in the calculations, as the system cannot determine which interest rate to apply for that specific maturity date.
  Cause:
  
  Duplicate Maturity Dates: The primary cause of this error is the presence of multiple reference interest rates that share the same maturity date within the yield curve.
