I have an Excel Destination in My DFT and i am loading the data from SQL Server, i do not have any Unique Identity columns at my source system hence i added a column called Insert date that takes the value form Getdate(), My requirement is if i am executing my SSIS package more than once my Excel destination is been loaded with duplicate records, How to mitigate the same, i am unable to use lookup here as lookup works with Database Table level only. Kindly suggest.
