  The SAP error message "PG490 Unlock in Change mode is not possible (missing authorization)" typically occurs when a user attempts to unlock an object in change mode but lacks the necessary authorizations to perform that action. This error is often encountered in the context of transport management or when working with development objects in the SAP system.
  Cause:
  
  Missing Authorizations: The user does not have the required authorizations to unlock the object. This could be due to missing roles or permissions in their user profile.
  Object Locking: The object may be locked by another user or process, and the current user does not have the necessary rights to unlock it.
  Transport Request Issues: If the object is part of a transport request, the user may not have the necessary authorizations to modify or unlock objects within that request.
