This error can arise in various scenarios, such as when trying to update or delete external references associated with a CRM object.
  Cause:
  
  Object Locking: The object you are trying to modify may be locked by another transaction or user, preventing changes.

  Authorization Issues: The user may not have the necessary permissions to modify the external references for the specified object.
  
  Solution:
  
  Check Object Locking: Ensure that the object is not locked by another user or transaction. You can use transaction code SM12 to check for locks and release them if necessary.
