How To Create a Gross Margin

I would like a report that shows sales price and cost(per item master) in AX 2009. Is there an easy way to do this?#### Is there a good report to show gross margin by product (item) for a given period of time?

AR → Reports → Statistics → Customer → Gross margin by item

It is not having any period selection, which need to changed as per your requirement.

To see between the dates, Apply a range on Date(InvoiceDate) field on Customer Invoice Journal table.
