• What is the cause and solution for SAP error message /SCWM/MONITOR138 - LUWs of queue &1 in status NOSEND must be picked up by the application ?

  The SAP error message /SCWM/MONITOR138 indicates that there are Logical Unit Works (LUWs) in a queue that are in the status "NOSEND." This means that these LUWs have not been processed or sent to the relevant application for further action. This situation can occur in the context of SAP Extended Warehouse Management (EWM) when there are issues with the processing of warehouse tasks or other related activities.
  Cause
  The "NOSEND" status typically arises due to one or more of the following reasons:
  
  Application Issues: The application that is supposed to process the LUWs may not be running or may have encountered an error.
  Configuration Issues: There may be configuration problems in the EWM system or in the integration with other systems (like SAP ERP or other external systems).
  Network Issues: Connectivity problems between the EWM system and the application can prevent LUWs from being sent.
  Data Issues: There may be data inconsistencies or errors in the LUWs that prevent them from being processed.
  Queue Management: The queue management settings may not be properly configured, leading to LUWs being stuck in the queue.
  
  Solution
  To resolve the issue, you can follow these steps:
  
  
  Check Application Status: Ensure that the application responsible for processing the LUWs is running correctly. Look for any error messages or logs that might indicate issues.
  
  
  Review Configuration: Verify the configuration settings in the EWM system and ensure that they are correctly set up for the integration with the application.
  
  
  Check Network Connectivity: Ensure that there are no network issues preventing communication between the EWM system and the application.
  
  
  Analyze LUWs: Use transaction codes like /SCWM/MON to monitor the LUWs and check for any specific errors or warnings associated with them. Look for any data inconsistencies that might be causing the issue.
  
  
  Reprocess LUWs: If the underlying issue has been resolved, you may need to manually reprocess the LUWs. This can often be done through the EWM monitor or by using specific transaction codes to trigger the processing.
  
  
  Consult Logs: Check the application logs and the EWM logs for any additional error messages that can provide more context on why the LUWs are in the "NOSEND" status.
  
  
  Contact Support: If the issue persists and you are unable to resolve it, consider reaching out to SAP support for further assistance.
