• What is the cause and solution for SAP error message HL660 - Successful connection test with RFC destination: '&1' ?

  The SAP error message HL660 indicates that a successful connection test was performed with the specified RFC (Remote Function Call) destination, denoted by &1. This message is typically informational rather than an error, meaning that the connection to the RFC destination is functioning correctly.
  Cause:
  
  The message HL660 is generated when you test an RFC destination in SAP, and the test is successful. It confirms that the connection settings (like the target system, user credentials, and network settings) are correctly configured and that the SAP system can communicate with the specified destination.
  
  Solution:
  Since HL660 indicates a successful connection, there is no action required to resolve an error. However, if you are expecting an error or if you are troubleshooting a different issue, consider the following steps:
  
  
  Verify RFC Destination Configuration: Ensure that the RFC destination is configured correctly in transaction SM59. Check the connection parameters, such as the target host, system number, client, user, and password.
  
  
  Check Network Connectivity: If you are experiencing issues with the application that uses this RFC destination, ensure that there are no network issues preventing communication between the SAP systems.
  
  
  Review Logs: If you are facing issues elsewhere, check the application logs or system logs (transaction SM21) for any related error messages that might provide more context.
  
  
  Test Functionality: If you are trying to perform a specific function using the RFC destination, ensure that the function module or BAPI you are calling is available and functioning correctly in the target system.
  
  
  User Authorizations: Ensure that the user credentials used for the RFC connection have the necessary authorizations to perform the required actions in the target system.
