• What is the cause and solution for SAP error message AV421 - & & -> Error with send status of remote program ?

  The SAP error message AV421, which indicates "Error with send status of remote program," typically occurs in the context of remote function calls (RFC) or when trying to communicate with a remote system. This error can arise due to various reasons, including network issues, configuration problems, or issues with the remote system itself.
  Causes of AV421 Error
  
  
  Network Issues: Problems with the network connection between the SAP system and the remote system can lead to this error. This could include firewalls blocking communication, network outages, or misconfigured network settings.
  
  
  RFC Destination Configuration: The RFC destination may not be configured correctly. This includes incorrect settings for the target system, such as the system ID, client number, user credentials, or connection type.
  
  
  Remote System Issues: The remote system may be down, unresponsive, or experiencing its own issues that prevent it from processing requests.
  
  
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to execute the remote function.
  
  
  Timeouts: If the remote function call takes too long to respond, it may time out, leading to this error.
  
  
  Solutions to AV421 Error
  
  
  Check Network Connectivity: Ensure that there is a stable network connection between the SAP system and the remote system. You can use tools like ping or traceroute to diagnose network issues.
  
  
  Verify RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check the configuration of the RFC destination that is causing the error.
  Ensure that the connection parameters (such as the target host, system number, client, user, and password) are correct.

  Check Remote System Status: Ensure that the remote system is up and running. You may need to contact the administrator of the remote system to verify its status.
  
  
  Review Authorizations: Make sure that the user credentials used for the RFC connection have the necessary authorizations to execute the required functions on the remote system.
  
  
  Increase Timeout Settings: If the remote function call is timing out, consider increasing the timeout settings in the RFC destination configuration.
