  The SAP error message RSDRO108 indicates that there was a communication error during an RFC (Remote Function Call) operation. This error can occur in various scenarios, particularly when dealing with data extraction or communication between different SAP systems or between an SAP system and an external system.
  Causes of RSDRO108
  
  
  Network Issues: Problems with the network connection between the SAP systems can lead to communication errors. This could be due to network outages, firewall settings, or incorrect routing.
  
  
  RFC Destination Configuration: The RFC destination may not be configured correctly. This includes incorrect connection parameters, such as the target system's IP address, port number, or user credentials.
  
  
  System Availability: The target system may be down or not available for communication. This could be due to maintenance, system crashes, or other operational issues.
  
  
  Authorization Issues: The user credentials used for the RFC call may not have the necessary authorizations to perform the requested operation.
  
  
  Timeout Settings: If the RFC call takes too long to respond, it may time out, leading to this error.
  
  
  SAP Notes: There may be known issues or bugs related to the specific version of SAP you are using, which can be resolved by applying relevant SAP Notes.
