• What is the cause and solution for SAP error message /SCMTMS/MULTIPLE_WND001 - Complete the task in the other window or wait for it to finish ?

  The SAP error message /SCMTMS/MULTIPLE_WND001 typically occurs in the SAP Transportation Management System (TMS) when a user attempts to perform an action that is already being processed in another session or window. This is a concurrency control mechanism to prevent data inconsistencies and conflicts that can arise from simultaneous operations on the same data.
  Cause:
  
  Multiple Sessions: The user has opened multiple sessions or windows of the SAP GUI and is trying to perform the same action in more than one session.
  Long-Running Processes: A process initiated in one session is still running, and the user tries to initiate the same process in another session.
  Locking Mechanism: SAP uses a locking mechanism to ensure data integrity, and if a lock is held by one session, other sessions will be blocked from performing the same action.
  
  Solution:
  
  Complete the Task in the Other Window: If you have another session open where the task is being processed, complete that task before trying again in the current session.
  Wait for the Process to Finish: If the task is taking longer than expected, you may need to wait until it completes. You can check the status of the process in the other session.
  Close Unused Sessions: If you have multiple sessions open, consider closing the ones that are not needed to avoid confusion and potential conflicts.
  Check for Background Jobs: If the process is running as a background job, you can check the job status using transaction code SM37 to see if it has completed.
  Log Off and Log Back In: If the issue persists and you cannot identify the session holding the lock, logging off and back into the system may help clear any stale locks.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks) and SM37 (to monitor background jobs).
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message.
  User Training: Ensure that users are trained on how to manage sessions effectively to avoid this error in the future.
  
  If the problem continues after trying the above solutions, it may be necessary to consult with your SAP Basis team or support for further investigation.
