• What is the cause and solution for SAP error message /SCWM/MEDI081 - &1 start of retry number &2; process objects that were previously locked ?

  The SAP error message /SCWM/MEDI081 typically indicates that there is a problem with the processing of a message in the Extended Warehouse Management (EWM) system. This error occurs when the system attempts to process objects that are currently locked, which can happen for various reasons, such as ongoing transactions or processes that have not yet completed.
  Cause:
  
  Locked Objects: The primary cause of this error is that the system is trying to access or process objects (like stock, handling units, or warehouse tasks) that are currently locked by another process or transaction.
  Concurrency Issues: Multiple processes trying to access the same object simultaneously can lead to locking issues.
  Long-running Transactions: If a transaction takes too long to complete, it can lead to other processes being unable to access the locked objects.
  System Configuration: Incorrect configuration or settings in the EWM system can also lead to locking issues.
  
  Solution:
  
  Identify Locked Objects: Use transaction codes like SM12 to identify which objects are locked and by which user or process. This can help you understand the source of the locking issue.
  Wait and Retry: The error message indicates that the system will attempt to retry the operation. If the locking is temporary, waiting for a few moments may resolve the issue.
  Release Locks: If you identify that a lock is held unnecessarily (e.g., a user has left a transaction open), you can manually release the lock using transaction SM12. However, be cautious when doing this, as it may disrupt ongoing processes.
  Optimize Processes: Review and optimize the processes that are causing locks. This may involve breaking down long-running transactions or ensuring that processes are not competing for the same resources.
  Check System Performance: Ensure that the system is performing optimally. High load or performance issues can exacerbate locking problems.
  Consult SAP Notes: Check for any relevant SAP Notes that may address known issues or provide patches related to this error.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to check system logs), and SLG1 (to view application logs) for troubleshooting.
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance, especially if it is affecting business operations.
  Documentation: Review the SAP EWM documentation for best practices on managing locks and optimizing warehouse processes.
  
  By following these steps, you should be able to diagnose and resolve the /SCWM/MEDI081 error effectively.
