Hi Raghu,
As mentioned by you that file has been archived after processing is fine. The overall objective of Duplicate File check is if the same file has been processed earlier, it should not be processed again (I expect that once file is processed, its details should be stored somewhere internally by adapter engine). But in my case it is being processed again and again despite the fact that I have same file name and parameter duplicate file check selected.
Regards,
Abhi
