  Cause:
  
  Invalid Parameter: The parameter specified in the target mapping may not exist or may be incorrectly defined.
  Missing Configuration: The target mapping may be missing required configuration settings or parameters.
  Inconsistent Data: There may be inconsistencies in the data or configuration settings related to the Fiori application.

  If a parameter is optional, consider removing it from the target mapping to see if that resolves the issue.
  
  
  
  Review Application Configuration:
  
  Check the application configuration in the backend (e.g., OData service) to ensure that it is set up correctly and that all required parameters are defined.

  If the issue arose after a transport, verify that all necessary objects were included in the transport request and that they were successfully imported into the target system.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific Fiori application to understand the required parameters and their expected values.
  
  
  
  Debugging:
