Advance Pricing with non stock items

Hi friends,

I am trying to attach advance pricing to a non stock item with line type as 'N '.I  have checked the edit item master flag for the line type. The stocking type for the item is 'N'.Advance price is turned on.

I have to attach adv.price to the sales order for the non stock item as this is needed for localisation module.

Any information shared will be highly appriciated.
