It would be helpful if you explain more thoroughly. Classic? Evo~ERP? Date of software update? What are your settings for the report? Does the system have a price for the items? Does the SO? Was the WO made via SO-N or manually?
 
Looking at my own, work order made with SO-N and where the system has a Price, the Price is pulled in. For items without a Price in the Item record there is no Price. Also, for WO's made manually for stock there is no Price.
