How to delete the duplicate rows present in the parent table & insert the latest duplicate record into the parent table linked with the child table.

Question

I have a master table and i need to import the rows into the parent and child table.
Master table name is Flatfile_Inventory
Parent Table name is INVENTORY
Child Tables name are INVENTORY_AMOUNT,INVENTORY_DETAILS,INVENTORY_VEHICLE,
Error details will be goes to LOG_INVENTORY_ERROR
I have 4 duplicate rows in the Flatfile_Inventory which i have already inserted in the Parent and child table.
Again when i run the query using stored procedure,
its tells that all the 4 rows are duplicate and will move to the Log_Inventory_Error.
I need is if i have the duplicate rows in the flatfile_Inventory when i start inserting into the parent and child table the already inserted row have the unique ID i
must identify it and delete that row in the both parent and chlid table.And latest row must get inserted into the Parent and child table from Flatfile_Inventory.
Please help me to write the query i have attached the Full stored procedure Script..
