  Incorrect Interface Configuration: The interface might not be set up correctly, or the key fields may not have been properly assigned during the configuration process.

  Check Interface Configuration:
  
  Go to the AIF configuration for the specific interface (transaction code: /AIF/IF_CONFIG).

  Review Data Model:
  
  Check the data model associated with the interface to ensure that it is correctly defined and that the key fields are present.
  
  
  
  Transport and Activation:
