• What is the cause and solution for SAP error message L6026 - Communication terminated although no end record was received ?

  The SAP error message L6026 ("Communication terminated although no end record was received") typically occurs in the context of the Logistics Execution (LE) module, particularly during the processing of inbound or outbound deliveries. This error indicates that the communication between the SAP system and an external system (like a warehouse management system or a third-party logistics provider) was interrupted before the expected end record was received.
  Causes:
  
  Network Issues: Temporary network disruptions can lead to communication failures.
  Timeout Settings: If the processing time exceeds the configured timeout settings, the connection may be terminated.
  Configuration Errors: Incorrect settings in the communication interface or middleware can lead to this error.
  System Overload: High system load or resource constraints can cause delays in processing, leading to timeouts.
  Data Issues: Corrupted or incomplete data being sent or received can also cause communication failures.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the SAP system and the external system. This includes checking firewalls, routers, and any other network devices.
  Review Timeout Settings: Adjust the timeout settings in the SAP system or the external system to allow for longer processing times if necessary.
  Monitor System Performance: Check the performance of the SAP system and the external system to ensure they are not overloaded. Consider scaling resources if necessary.
  Review Configuration: Verify the configuration settings for the communication interface. Ensure that all parameters are correctly set up.
  Check Logs: Look at the application logs (transaction SLG1) and system logs (transaction SM21) for any additional error messages or warnings that could provide more context.
  Data Validation: Ensure that the data being sent and received is complete and correctly formatted. Validate the data against expected formats and structures.
  Retry Mechanism: Implement a retry mechanism in the communication process to handle transient errors gracefully.
