  The SAP error message "SATC_RUN_TIME311 DSP: Cannot establish connection to RFC destination <&1>" indicates that there is an issue with establishing a connection to a Remote Function Call (RFC) destination in your SAP system. This can occur for various reasons, and here are some common causes, solutions, and related information:
  Causes:
  
  Incorrect RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system.
  Network Issues: There may be network connectivity issues between the SAP system and the target system defined in the RFC destination.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations.
  Target System Down: The target system that the RFC destination points to may be down or not reachable.
  Firewall Restrictions: Firewalls or security settings may be blocking the connection to the target system.
  SAP Gateway Issues: The SAP Gateway service may not be running or may be misconfigured.
  
  Solutions:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination <&1> and check its configuration settings.
