This error can occur in various scenarios, particularly when dealing with secure communications or when sending data between different SAP systems.
  Causes:
  
  Incorrect Configuration: The SSF settings may not be properly configured in the SAP system. This includes issues with the SSF profile or the cryptographic settings.
  Missing or Incorrect RFC Destination: The RFC destination may not be correctly defined, or the recipient list may be missing required entries.
  Authorization Issues: The user or service account executing the RFC may not have the necessary authorizations to access the SSF or the recipient list.
  Network Issues: There may be network connectivity problems between the systems involved in the RFC call.
  Expired or Invalid Certificates: If the communication relies on certificates, they may have expired or been revoked.
  
  Solutions:
  
  
  Check SSF Configuration:
  
  Go to transaction SSFC to review the SSF settings.
  Ensure that the SSF profile is correctly configured and that the necessary cryptographic algorithms are available.
