  Network Issues: There may be network connectivity issues between the SAP systems involved. This could be due to firewalls, routing problems, or other network-related issues.
  
  
  Authorization Issues: The user or service account being used to invoke the RFC may not have the necessary authorizations to access the target system or execute the required function.
  
  
  Target System Down: The target system that the RFC destination points to may be down or not reachable.
  
  
  Function Module Issues: The function module being called may not exist in the target system, or it may have been changed or deleted.
