  The SAP error message /IWFND/CM_BEC013 RFC call was not successful because of communication failure '&1' typically indicates that there was a problem with the Remote Function Call (RFC) communication between the SAP system and another system or service. This error can occur in various scenarios, particularly when dealing with OData services or when the SAP Gateway is trying to communicate with backend systems.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP Gateway and the backend system.
  RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system.
  Backend System Down: The backend system that the SAP Gateway is trying to reach may be down or not responding.
  Authorization Issues: The user credentials used for the RFC call may not have the necessary authorizations.
  Timeouts: The RFC call may be timing out due to long processing times or heavy load on the backend system.
  Firewall Restrictions: Firewalls or security settings may be blocking the communication between systems.
  
  Solutions:
  
  
  Check Network Connectivity:
  
  Use tools like ping or traceroute to check the connectivity between the SAP Gateway and the backend system.
