  The SAP error message /DSD/ME081 Tour &1 - Existing MW queue is locked - deletion not possible typically occurs in the context of the SAP Direct Store Delivery (DSD) module, particularly when dealing with tours and the associated mobile warehouse (MW) queues. This error indicates that there is an attempt to delete a tour that is currently locked due to an existing mobile warehouse queue.
  Cause:
  
  Locked MW Queue: The primary cause of this error is that there is an existing mobile warehouse queue associated with the tour that is currently locked. This could happen if there are ongoing transactions or processes that are using the queue.
  Active Processes: There may be active processes or transactions that are preventing the deletion of the tour. For example, if goods are being processed or if there are open deliveries linked to the tour.
  User Lock: Another user or process may have locked the queue, preventing any modifications or deletions.
  
  Solution:
  
  Check for Active Processes: Investigate if there are any active processes or transactions that are using the mobile warehouse queue. You can do this by checking the relevant transactions in SAP that might be linked to the tour.
  Unlock the Queue: If you have the necessary permissions, you can unlock the queue. This may involve terminating any active processes or transactions that are using the queue.
  Wait for Completion: If the queue is locked due to ongoing processes, you may need to wait until those processes are completed before attempting to delete the tour again.
  Consult with Users: If other users are involved, communicate with them to ensure that they are not using the queue or the tour in question.
  Check for System Locks: Use transaction codes like SM12 (to check for user locks) or SM21 (to check system logs) to identify any locks that may be affecting the queue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /DSD/ME81 for managing tours and /DSD/ME80 for monitoring mobile warehouse activities.
