GR464 - Details

• The SAP error message GR464, which states "The library is being edited by another user," typically occurs in the context of SAP's graphical user interface (GUI) when multiple users attempt to edit the same library or object simultaneously. This can happen in various SAP modules, particularly in areas related to development or configuration, such as ABAP development or customizing.
  
  Cause:
  
  Concurrent Access: Another user is currently editing the same library or object, which locks it for editing to prevent conflicts.
  Session Issues: Sometimes, a previous session may not have been closed properly, leaving the object in a locked state.
  Transport Requests: If the object is part of a transport request, it may be locked for editing until the transport is completed or released.
  
  
  Solution:
  
  Wait and Retry: If another user is editing the library, the simplest solution is to wait until they finish and then try again.
