• What is the cause and solution for SAP error message CRM_MKT_EXTERNAL113 - Connection to COM server via RFC Gateway disconnected ?

  The SAP error message CRM_MKT_EXTERNAL113 indicates that there is a problem with the connection to the COM server via the RFC (Remote Function Call) Gateway. This error typically arises in scenarios where SAP CRM is trying to communicate with an external system or service, and the connection is lost or not established properly.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP system and the COM server.
  RFC Gateway Configuration: The RFC Gateway may not be configured correctly, or the connection parameters may be incorrect.
  COM Server Availability: The COM server may be down or not reachable due to maintenance or other issues.
  Timeout Settings: The connection may be timing out due to long processing times or delays in the COM server response.
  Firewall Restrictions: Firewalls or security settings may be blocking the communication between SAP and the COM server.
  Resource Limitations: The SAP system or the COM server may be running out of resources (e.g., memory, CPU) leading to disconnections.
  
  Solutions:
  
  Check Network Connectivity: Ensure that the network connection between the SAP system and the COM server is stable and functioning. You can use tools like ping or traceroute to diagnose network issues.

  Firewall Settings: Review firewall rules to ensure that the necessary ports for RFC communication are open and not being blocked.
  Monitor Resource Usage: Check the resource usage on both the SAP system and the COM server. If either system is under heavy load, consider optimizing performance or scaling resources.
  Logs and Traces: Review the SAP application logs (transaction SLG1) and the COM server logs for any additional error messages or clues that could help diagnose the issue.
