Problem : If y ou are trying to create in the Device Channels list a list item , what is there already . This results will be an error because the column alias prevents elements with the same alias can be created . Elements are therefore in this list also does not update ( while synchronizing)

Solution: The error can be ignored . This occurs in all lists and list elements in which a duplicate detection is active .
