I have a list of 'n' items and I run an import action on the list. The numbers of items in the list is now 'm'. How can I identify the items that were inserted in the current import.
The import file can contain the items that are already present in the list as well.
E.g : Initial List - 1, 2, 3, 4, 5
List after import - 1, 2, 3, 4, 5, 6, 7
Import file - 4, 5, 6, 7.
Is there a way where I can flag or identify only 6 and 7 ?
