  Causes of ALVHT203 Error
  
  
  Network Issues: Problems with the network connection between the systems can lead to RFC errors. This could be due to firewalls, routing issues, or network outages.
  
  
  Configuration Errors: Incorrect configuration of the RFC destination in the SAP system can cause this error. This includes incorrect settings in transaction SM59.
  
  
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to perform the requested operation.
  
  
  System Availability: The target system may be down or not reachable, leading to a failure in establishing the RFC connection.
  
  
  Timeouts: If the RFC call takes too long to respond, it may time out, resulting in this error.
  
  
  Version Compatibility: Incompatibility between different SAP versions or components can also lead to RFC connection issues.
