In standard SAP you have the provision to show the warehouse stock and bin stock, please have a look on existing thread
http://scn.sap.com/thread/3580410
Also few query
1) is this PRD/ PRODUCTION is a part of Production line side ?
2) the stock which is lying in PRD is for another production order for which production is in WIP so while releasing another production order why do you want to check the stock for new production order ?
