  SAP Error Message:
  WER427 - Copy not allowed, element &1 is not locked
  
  
  Cause:
  This error occurs when you attempt to copy or modify an object (such as a work breakdown structure element, network activity, or other project system elements) that is not currently locked by your user session. In SAP Project System (PS) or related modules, certain objects must be locked before changes can be made to ensure data consistency and prevent conflicts from simultaneous edits by multiple users.
  The message indicates that the system expects the element (identified by &1) to be locked by your user session before allowing the copy operation, but it is not locked.
  
  Explanation:
  
  Locking is a mechanism to prevent concurrent changes.
  If the element is not locked, the system assumes another user might be editing it or it is not reserved for editing.
  Copy operations often require the source element to be locked to ensure the data integrity during the copy
