How To Fix SWF_XI_ADAPTER407 - Inbound queue &1 (SMQ2) for process type &2 has LUW with errors

SAP Error Message - Details

• Message type: E = Error

• Message class: SWF_XI_ADAPTER - XI BPM: Messages

• Message number: 407

• Message text: Inbound queue &1 (SMQ2) for process type &2 has LUW with errors

What causes this issue?

You want to change the settings for inbound processing for a process
type. The change is not permitted in this case because the
process-type-specific queue contains an entry with errors.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The short text of the error message specifies which queue contains
errors. Copy the queue name and call transaction SMQ2. Start the
selection using the copied queue name.
Try to analyze and correct the problem, then restart the queue. Once the
entry with errors has been executed successfully, you must stop the
queue by using a stop entry and wait until the entry currently being
executed has been completed successfully. You can then change the
settings for inbound processing.
Tools for analyzing queue entries with errors:
Transaction SWF_TRC
If errors occur during inbound processing, the system writes a system
trace for component BC-BMT-WFM. The trace entries provide information
about the cause of the error. The trace also indicates whether it is a
temporary or permanent error. Since the system restarts the queue entry
if it is a temporary error, you only need to take action if the error is
permanent.
Note that it is not possible to start queue entries with errors if a
queue is stopped or not registered. Furthermore, a temporary queue entry
error becomes a permanent error after several unsuccessful restart
attempts.
Transaction ST22
The queue can have permanent error status due to an unforeseeable
runtime error. To limit the number of hits in ST22 as accurately as
possible, you can use the date and time of the runtime error either from
the trace (transaction SWF_TRC) or from the queue entry (transaction
SMQ2).

• What is the cause and solution for SAP error message SWF_XI_ADAPTER407 - Inbound queue &1 (SMQ2) for process type &2 has LUW with errors ?

  The SAP error message SWF_XI_ADAPTER407 indicates that there is an issue with the inbound queue (SMQ2) for a specific process type. This error typically occurs when there are errors in the Logical Unit of Work (LUW) that prevent the successful processing of messages in the queue.
  Cause:
  
  
  Message Processing Errors: The LUW may contain messages that have failed during processing due to various reasons, such as:
  
  Incorrect or missing data in the message.
  Issues with the target system or service that the message is trying to reach.
  Configuration errors in the integration scenario.
  Network issues or timeouts.
  
  
  
  System Configuration Issues: There may be misconfigurations in the SAP system or in the middleware (like SAP PI/PO) that are causing the messages to fail.
  
  
  Resource Limitations: The system may be running low on resources (e.g., memory, processing power), which can lead to message processing failures.
  
  
  Solution:
  
  
  Check the Inbound Queue: 
  
  Go to transaction code SMQ2 to view the inbound queue.
  Identify the specific LUW that has errors and analyze the details of the message.
  
  
  
  Analyze Error Details:
  
  Look for error messages or logs associated with the failed LUW. This can provide insights into what went wrong.
  Check the application logs (transaction SLG1) for any related error messages.
  
  
  
  Correct the Data: 
  
  If the error is due to incorrect or missing data, correct the data in the source system or the message payload.
  
  
  
  Check Configuration: 
  
  Review the configuration of the process type in the integration scenario to ensure that it is set up correctly.
  Verify that the target system is reachable and properly configured to accept messages.
  
  
  
  Reprocess the LUW: 
  
  Once the issues are resolved, you can reprocess the LUW from the inbound queue. This can typically be done by selecting the LUW and choosing the option to reprocess it.
  
  
  
  Monitor System Resources: 
  
  Ensure that the system has adequate resources to handle message processing. Monitor memory and CPU usage to identify any bottlenecks.
  
  
  
  Consult Documentation: 
  
  Refer to SAP Notes and documentation related to the specific error message for additional troubleshooting steps and solutions.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SMQ2: To view and manage inbound queues.
  SLG1: To check application logs for error messages.
  
  
  
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address specific issues related to this error message.
  
  
  Integration Scenarios: Familiarize yourself with the specific integration scenario and process type that is generating the error, as this can provide context for troubleshooting.
  
  
  By following these steps, you should be able to identify the root cause of the SWF_XI_ADAPTER407 error and implement a solution to resolve it.
