• What is the cause and solution for SAP error message TPDAPI005 - Application server of debuggee RFC (&1, &2) does not match debugger (&3) ?

  The SAP error message TPDAPI005 indicates a mismatch between the application server of the debugged program (debuggee) and the debugger that is currently being used. This typically occurs when you are trying to debug a program that is running on a different application server than the one where the debugger is running.
  Cause:
  
  Different Application Servers: The program you are trying to debug is running on a different application server than the one where the debugger is initiated.
  Incorrect Configuration: The debugger might be configured to connect to a different instance or server.
  Network Issues: There could be network issues preventing the debugger from connecting to the correct application server.
  
  Solution:
  
  
  Check Application Server: Ensure that the program you are trying to debug is running on the same application server as the debugger. You can check the server details in the SAP GUI by using transaction SM51 to see the list of application servers and their statuses.
  
  
  Start Debugger on Correct Server: If the program is running on a different server, you need to start the debugger on that specific server. You can do this by logging into the correct application server and then starting the debugger.
  
  
  Use Remote Debugging: If you need to debug a program running on a different server, consider using remote debugging features provided by SAP. This may involve setting up the debugger to connect to the remote server.
  
  
  Check RFC Connections: Ensure that the RFC connections are correctly configured and that there are no issues with connectivity between the servers.
  
  
  Restart the Debugger: Sometimes, simply restarting the debugger or the SAP GUI can resolve temporary issues.
