• What is the cause and solution for SAP error message CRM_MKT_EXTERNAL110 - Connection to RFC Gateway &1 created; RFC handle: &2 ?

  The SAP error message CRM_MKT_EXTERNAL110 indicates that there is an issue related to the connection to the RFC (Remote Function Call) Gateway. This message typically appears when there is a problem establishing a connection to an external system or service, which is often required for integration scenarios in SAP CRM (Customer Relationship Management).
  Cause
  The error message can be caused by several factors, including:
  
  Network Issues: There may be network connectivity problems between the SAP system and the external system.
  RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system. This includes incorrect parameters such as the target host, system number, client, user credentials, etc.
  Gateway Issues: The SAP Gateway might not be running or may be misconfigured.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to access the external system.
  Firewall Restrictions: Firewalls may be blocking the connection to the external system.
  
  Solution
  To resolve the issue, you can follow these steps:
  
  
  Check Network Connectivity:
  
  Ensure that the SAP system can reach the external system over the network. You can use tools like ping or telnet to test connectivity.
  
  
  
  Verify RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check the configuration of the RFC destination that is being used. Ensure that all parameters (like target host, system number, client, user, and password) are correct.
  Test the connection from SM59 to see if it is successful.
  
  
  
  Check Gateway Status:
  
  Ensure that the SAP Gateway is running. You can check the status using transaction SMGW.
  If the gateway is not running, you may need to restart it.
  
  
  
  Review Authorizations:
  
  Ensure that the user credentials used in the RFC destination have the necessary authorizations to access the external system.
  
  
  
  Firewall Configuration:
  
  Check if there are any firewall rules that might be blocking the connection. Ensure that the necessary ports are open for communication.
  
  
  
  Check Logs:
  
  Review the system logs (transaction SM21) and the developer trace files (transaction ST11) for any additional error messages that might provide more context.
