  The SAP error message EHFND_INT_COMN102 indicates an RFC (Remote Function Call) communication error. This error typically arises when there is a problem with the connection between the SAP system and the target system or when there is an issue with the function module being called.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP systems.
  RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system.
  Authorization Issues: The user credentials used for the RFC call may not have the necessary authorizations.
  Function Module Issues: The function module being called may not exist, may be inactive, or may have been changed.
  System Load: The target system may be overloaded or down, causing the RFC call to fail.
  Firewall or Security Settings: Firewalls or security settings may be blocking the communication.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there is proper network connectivity between the systems. You can use tools like ping or traceroute to diagnose network issues.
  Verify RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check the configuration of the RFC destination (e.g., connection type, target host, system number).
  Test the connection using the "Connection Test" button.
  
  
  Check Authorizations: Ensure that the user credentials used for the RFC call have the necessary authorizations to execute the function module.
  Validate Function Module:
  
  Check if the function module exists in the target system.

  Monitor System Load: Check the performance and load of the target system. If it is overloaded, consider optimizing the system or scheduling the RFC calls during off-peak hours.
  Review Firewall/Security Settings: Ensure that any firewalls or security settings allow communication between the two systems.
