• What is the cause and solution for SAP error message CNV_PE101 - Check of RFC connection &1 ended with errors ?

  The SAP error message CNV_PE101: Check of RFC connection &1 ended with errors typically indicates that there is an issue with the Remote Function Call (RFC) connection to a specified system. This error is often encountered during data migration or system conversion processes, particularly when using tools like SAP S/4HANA Migration Cockpit or SAP Landscape Transformation (SLT).
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP system and the target system.
  RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system. This includes incorrect parameters such as the target system's hostname, system number, client, user credentials, etc.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to perform the required operations.
  Service Availability: The target system may not be running or the required services (like the SAP Gateway) may not be active.
  Firewall Restrictions: Firewalls or security settings may be blocking the connection between the systems.
  
  Solutions:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination that corresponds to the error message (indicated by &1).
  Test the connection using the "Connection Test" button to see if it is successful. If not, check the configuration settings.
  
  
  
  Verify Network Connectivity:
  
  Ensure that the network connection between the two systems is stable and operational. You can use tools like ping or traceroute to check connectivity.
  
  
  
  Review User Authorizations:
  
  Ensure that the user specified in the RFC destination has the necessary authorizations to access the target system and perform the required operations.
  
  
  
  Check Target System Status:
  
  Ensure that the target SAP system is up and running and that all necessary services are active.
  
  
  
  Firewall and Security Settings:
  
  Check if there are any firewall rules or security settings that might be blocking the RFC connection. Ensure that the necessary ports are open.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and the developer trace files (transaction ST11) for any additional error messages that might provide more context about the issue.
  
  
  
  Related Information:
