  The SAP error message /SCWM/DELIVERY_UI079 indicates that a transportation unit (TU) is currently being updated, which prevents further actions on it until the update is complete. This error typically occurs in the context of the Extended Warehouse Management (EWM) module when trying to perform operations on a transportation unit that is locked due to an ongoing process.
  Cause:
  
  Concurrent Updates: The transportation unit is being updated by another user or process, which locks it for modifications.
  Long-running Processes: A background job or a lengthy transaction is currently processing the transportation unit.
  System Locking Mechanism: SAP uses locking mechanisms to ensure data integrity, and if a TU is locked, it cannot be accessed until the lock is released.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for a few moments and then retry the operation. If the update is completed, the lock will be released.
  Check for Active Processes: Use transaction codes like SM12 (to check for locks) or SM37 (to check for background jobs) to identify if there are any active processes that are holding the lock on the transportation unit.
  Contact the User: If you identify a specific user or process that is holding the lock, you may need to contact them to understand the situation or request them to complete their transaction.
  System Administrator Intervention: If the lock persists and you cannot identify the cause, you may need to involve a system administrator to investigate further. They can analyze the system logs and determine if there is a need to manually release the lock.
  Review Custom Code: If you have custom developments that interact with transportation units, review them to ensure they are not causing unnecessary locks.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to view system logs), and SM37 (to monitor background jobs).
