  The SAP error message FDT_EXPRESSIONS409: Delay must not be negative typically occurs in the context of using the SAP Fiori Design Studio or when working with expressions in SAP applications. This error indicates that a delay value that has been specified in a certain context (like a timer, animation, or delay in processing) is negative, which is not allowed.
  Cause:
  
  Negative Delay Value: The most direct cause of this error is that a negative value has been assigned to a delay parameter in an expression or configuration.
  Incorrect Logic: There may be a logical error in the code or configuration that results in a negative value being calculated or passed where a positive value is expected.
  Data Input Issues: If the delay value is derived from user input or external data, there may be issues with the data being provided.
  
  Solution:
  
  Check Delay Values: Review the expressions or configurations where the delay is set. Ensure that all delay values are non-negative.
  Debugging: If the delay value is calculated dynamically, add debugging statements to trace the value being assigned. This will help identify where the negative value is coming from.
  Validation: Implement validation checks to ensure that any input or calculated values for delays are checked before being used. If a negative value is detected, handle it appropriately (e.g., set it to zero or raise a user-friendly error).
  Review Logic: Go through the logic of your application to ensure that the calculations leading to the delay value are correct and do not inadvertently produce negative results.
