• What is the cause and solution for SAP error message RSAPI_CTC003 - Disconnecting BW system &1 from BW source system &2... ?

  The SAP error message RSAPI_CTC003 indicates that there is a disconnection issue between a BW (Business Warehouse) system and a BW source system. This can occur for various reasons, and understanding the cause is essential for troubleshooting and resolving the issue.
  Causes:
  
  
  Network Issues: Connectivity problems between the BW system and the source system can lead to disconnections. This could be due to network outages, firewall settings, or incorrect network configurations.
  
  
  System Configuration: Incorrect configuration settings in either the BW system or the source system can cause disconnections. This includes settings related to the RFC (Remote Function Call) destination.
  
  
  Timeout Settings: If the timeout settings for the connection are too low, long-running queries or data loads may exceed the timeout limit, resulting in disconnection.
  
  
  Resource Limitations: If either the BW system or the source system is under heavy load or has insufficient resources (CPU, memory), it may lead to disconnections.
  
  
  Transport Layer Issues: Problems in the transport layer, such as issues with the SAP kernel or transport protocols, can also lead to disconnections.
  
  
  Solutions:
  
  
  Check Network Connectivity: Ensure that there are no network issues between the BW system and the source system. You can use tools like ping or traceroute to diagnose connectivity.
  
  
  Review RFC Configuration: Verify the RFC destination settings in both systems. Ensure that the connection parameters are correct and that the connection is working properly. You can test the RFC connection using transaction SM59.
  
  
  Adjust Timeout Settings: If timeout settings are too low, consider increasing them. This can be done in the RFC destination settings or in the BW system configuration.
  
  
  Monitor System Resources: Check the performance and resource utilization of both systems. If either system is under heavy load, consider optimizing performance or scaling resources.
  
  
  Check Logs: Review the system logs (transaction SM21) and the BW process logs for any additional error messages or warnings that could provide more context about the disconnection.
  
  
  Update SAP Kernel: Ensure that both systems are running on compatible and up-to-date versions of the SAP kernel. Sometimes, kernel bugs can lead to connectivity issues.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address known issues related to this error message.
