    In SCD2 , if we insert same row with same data can it insert ? or not?

      The purpose of SCD 2 is to track all the history of changes, when you send the new same row, the new row will not be inserted because you already have that row in your target and this is the normal behaviour because only few rows gets changes , remaining all are old rows only
