• What is the cause and solution for SAP error message 0D143 - Name of application server &1 is invalid ?

  The SAP error message 0D143 indicates that the name of the application server specified is invalid. This error typically occurs when there is a misconfiguration in the SAP system settings or when the application server name is incorrectly specified in the connection settings.
  Causes:
  
  Incorrect Server Name: The application server name provided in the configuration is misspelled or does not exist in the system.
  Network Issues: There may be network connectivity issues preventing the system from reaching the specified application server.
  Configuration Errors: The SAP system configuration (e.g., in the instance profile or the SAP GUI) may have incorrect entries.
  Server Not Running: The application server may not be running or may have been shut down.
  DNS Issues: If the server name is resolved through DNS, there may be issues with DNS configuration.
  
  Solutions:
  
  Verify Server Name: Check the application server name in the configuration settings (e.g., SAP GUI, RFC destination) and ensure it is spelled correctly.
  Check Server Status: Ensure that the application server is up and running. You can check this using transaction SM51 to see the list of active application servers.
  Network Connectivity: Test the network connection to the application server. You can use tools like ping or telnet to check connectivity.
  Review Configuration: Go through the SAP configuration settings to ensure that all entries related to the application server are correct. This includes checking the instance profile and any relevant parameters.
  DNS Configuration: If the server name is resolved through DNS, ensure that the DNS settings are correct and that the server name can be resolved to the correct IP address.
  Use IP Address: As a temporary workaround, you can try using the IP address of the application server instead of the server name to see if that resolves the issue.
