  The SAP error message LQ713 indicates a TCP/IP link creation error in a dependent system. This error typically occurs when there is an issue with the network configuration or connectivity between the SAP systems involved. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  Network Configuration Issues: Incorrect network settings, such as IP addresses, hostnames, or ports, can lead to connectivity problems.
  Firewall Restrictions: Firewalls may be blocking the necessary ports for communication between the systems.
  SAP Gateway Configuration: The SAP Gateway might not be configured correctly, preventing the establishment of a TCP/IP connection.
  Dependent System Not Running: The dependent system (the system you are trying to connect to) may not be up and running.
  DNS Resolution Issues: If the hostname cannot be resolved to an IP address, the connection will fail.
  Incorrect RFC Destination: The RFC destination in the SAP system may be incorrectly configured.
  
  Solutions:
  
  
  Check Network Configuration:
  
  Verify the IP address and hostname of the dependent system.
  Ensure that the correct ports are being used for communication.
  
  
  
  Firewall Settings:
  
  Check firewall settings on both the source and dependent systems to ensure that the necessary ports (usually 3200 for SAP) are open.
  
  
  
  SAP Gateway Configuration:
  
  Use transaction code SMGW to check the status of the SAP Gateway.
  Ensure that the gateway is running and properly configured.
  
  
  
  Check Dependent System Status:
  
  Ensure that the dependent system is up and running. You can try to ping the system to check connectivity.
  
  
  
  DNS Resolution:
  
  Test DNS resolution by using the nslookup command to ensure that the hostname resolves correctly to an IP address.
  
  
  
  RFC Destination Configuration:
  
  Go to transaction code SM59 and check the configuration of the RFC destination.
  Test the connection from this transaction to see if it is successful.
