  SAP Error Message:
  
  WSTRN104 Some prepacks cannot be changed; check logs
  
  Cause
  This error occurs in SAP Warehouse Management (WM) or Extended Warehouse Management (EWM) when you attempt to change or update prepack handling units (HUs), but some of these prepacks are locked, already processed, or in a status that does not allow changes. The system prevents modification to maintain data consistency and integrity.
  Common reasons include:
  
  The prepack HUs are already confirmed or partially confirmed in warehouse processes.
  The prepacks are involved in ongoing warehouse tasks or deliveries.
  The prepacks are in a status that disallows changes (e.g., already posted, blocked, or physically moved).
  There are inconsistencies or errors in the prepack structure or related documents.
  The user does not have the necessary authorizations to change the prepacks.
  
  
  Solution
  
  
  Check the Logs:
  
  The message advises to check the logs for detailed information about which prepacks cannot be changed and why.  
  
  In EWM, check the Warehouse Monitor or the relevant log transaction (e.g., /SCWM/PRPACKLOG or related).
  In WM, check the change logs or application logs (transaction SLG1) for messages related to the prepacks.
  
  
  
  Identify the Problematic Prepacks:
  
  From the logs, identify which prepacks are causing the issue and their current status.

  Release or Complete Related Processes:  
  
  If the prepacks are involved in open warehouse tasks, complete or cancel those tasks.
  If the prepacks are blocked, unblock them if appropriate.

  Authorization Check:
  
  Ensure the user has the necessary authorizations to change prepacks.
