• What is the cause and solution for SAP error message XC071 - Data transfer to &1 was stopped (start channel first) ?

  The SAP error message XC071 indicates that a data transfer to a specified target (denoted as &1) was halted because the corresponding communication channel has not been started. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is an attempt to send data to a target system without the necessary communication channel being active.
  Cause:
  
  Inactive Communication Channel: The most common cause of this error is that the communication channel responsible for transferring data to the target system is not started or is in an inactive state.
  Configuration Issues: There may be configuration issues in the integration scenario that prevent the channel from starting.
  System Issues: The SAP system or the middleware may be experiencing issues that prevent the channel from being activated.
  
  Solution:
  
  
  Start the Communication Channel:
  
  Go to the SAP PI/PO monitoring tools (like the Integration Engine or the Runtime Workbench).
  Navigate to the communication channel that corresponds to the target system.
  Check the status of the channel. If it is stopped, start it manually.
  
  
  
  Check Channel Configuration:
  
  Ensure that the configuration of the communication channel is correct. This includes checking the sender and receiver settings, adapter type, and any relevant parameters.
  Verify that the channel is not in a state that prevents it from starting (e.g., it may be in a "Stopped" or "Error" state).
  
  
  
  Review Logs and Traces:
  
  Check the logs for any errors or warnings that might indicate why the channel is not starting.
  Look for any relevant error messages in the Application Log (transaction SLG1) or the Integration Engine logs.
  
  
  
  Restart the Integration Engine:
  
  If the communication channel is still not starting, consider restarting the Integration Engine or the entire SAP PI/PO system, as this can sometimes resolve underlying issues.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support notes related to the specific version of SAP PI/PO you are using for any known issues or additional troubleshooting steps.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like SXMB_MONI for monitoring messages, SXI_MONITOR for monitoring the integration engine, and SXI_CACHE for checking the cache.
  SAP Notes: Check SAP Notes for any updates or patches that may address known issues related to communication channels.
  Community Forums: SAP Community and other forums can be helpful for finding similar issues faced by other users and their solutions.
  
  By following these steps, you should be able to resolve the XC071 error and successfully transfer data to the target system.
