Valuation Rate not found for item

I am creating a BOM via the “File import " functionality.
I am creating a finished product “Item FG” using " Item A”, “Item B” an d"Item C".

However the file upload is erroring with the message stating “Valuation Rate not found for Item A , Item B, Item C”.

I have set the valuation rate at the item master for each of the items (Item A, Item B, Item C ) as 0. Also in the csv file i have set the “Rate Of Materials Based On” as "Valuation rate " and also set the value as 0 for the rate items column etc.

Any idea on how can i ignore the error and still cause the BOM to be created without this error
